Any bug reports you have filed on the CentOS bug tracker?

You have to install 5.3 beta and test it yourself. Then
again if your "alleged problems" only surface in a 
conversation with your "fedora buddy" you have to have 
more than your word for it.

You can download and install, however, in order to
do:

yum update

or even:

yum install something

you have to register the system on one of your available
subscriptions.

That's how I experience it - I could be wrong?

Well I am. Now I've even tried it and on both centos-4 and centos-5 I had no 
problems authenticating with my public key when my shadow entry started 
with "!!".

If you truely want to lock an account (all access and use) then you have many 
things to consider including:

* .ssh/authorized_keys
* .forward
* crond
* atd
* running processes

I believe the differing "recommendations" is a result of the transitions
over the life of *IX systems. When I first began running real UNIX (TM)
on Dec and PC equipment (1978-1985), memory was slow, expensive and
limited. Ditto for HD space. In order to run even fairly basic systems
with any utility involving multi-tasking or multi-users, swap was need
to page memory. Tunables were provided for high/low water marks and
preferences for high/low priority processes. IIRC, initially there was
no oom kill capability.

Recommended swap at that time was at least two times real memory and 4
times for "heavily loaded" systems. If you were doing more, bump that
number appreciably. But it had severe costs when you maximum HD size
might be 40MB, so you didn't want to over-allocate.

Over time, memory/HD attributes and "flavors" of *IX changed.
Applications changed. Shared memory, libraries came into vogue.
Relocation became possible. ELF appeared.

All this stuff changed the real needs for swap. But old habits die hard.
So we still have conflicting recommendations floating around. Several on
this list have been successfully configuring 0 swap for their usage. For
other usage that may not be appropriate.


Summary: as it always has been, your application and load profile
determine the need. Since HD is so "cheap" now, I have a couple gig of
swap, but haven't seen it used since sometime in CentOS 5.0. Even when I
login in as multiple users and fire up several X/Gnome desktops for
each, no swap usage. There's probably been some swap used, but it wasn't
seen by me.

That's a silly recommendation, and never been true for Linux.  RedHat

I disagree with that. It has been true for linux for a long time, and is 
true even now. When was the last time you looked at the linux swap 
handling code ?


Recently, with large amounts of ram available on physical machines, eg > 
2 GB, you need to start reconsidering a part of that strategy based 
around the fact that if your machine is really using 2 GB+ of swap, 
there might be other problems that need fixing and the absurd levels of 
latency introduced by that would mean those other issues really need 
looking at.


I'd still go with 2xRAM size for swap size upto a swap size of 2 GB, 
then make it the same as RAM size, till you get to 32 GB, at which 
point, half of real RAM size till 128 GB. Beyond that point, you really 
should be doing some benchmarks and monitoring to work out how much swap 
you need, and where it needs to be.


The other school of thought that seems to be doing the rounds is, 2xRAM 
till 4 GB, then just leave swap at 4GB irrespective of what your real 
machine RAM is, as long as its a multiple of 4.

And then make that into an rpm? Or just work around the packaging system
on CentOS? 

Not a good idea.

There are some packages in the CentOS-Testing repository (which require
you to give feedback to the CentOS developers via
, there is Jason Litka's repository and there is
Remi Collet's repository.

But: If you have problems with the packages from there, then bug the
people you got the packages from - not CentOS.

Anyway, all of those means of distribution are way better than working
around package management.

Don't assume that because the bug is in php 5.1.6 that
upstream have not addressed it by backporting a fix see 
http://www.redhat.com/security/updates/backporting/?sc_cid=3093
Have you filed any bugs in bugs.centos.org or checked to 
see if the bug is present in CentOS?

There is no evidence supplied by yourself or by the OP that

With my usual jaundiced eye, my first thought is that the fault is not
the obvious one. So I suggest temporarily abandoning "The Usual
Suspects" (TM) - what a *great* movie.

Is it a consistent or sporadic issue? Is the controller an on-board or
after-market? If on-board, is the BIOS the latest? Have you checked
connections power/data cable connections? The number you mention makes
me think of a bad cable (or connections). Any pattern if it's recurring?
Temperature steady in the area? If you had a temporary rise/fall in
temperature it could have exposed weak connections, micro-fractures in
various cables, poor seating of memory, add-in cards, etc.

Any other messages, that might be related, in the log file when it
happens? I'm wondering if some spurious interrupt might be involved.

Have you memtested recently? ISTM that a memory error could "fool" the
system. Re-seated the memory?

How about the kernel version? On the latest kernel, 2.6.18-92.1.13.el5,
I recently got this.

Never seen before. Only once, so far. I've not yet investigated this. No
recent changes to the system since 5.0 but normal yum updates to current
5.2 status. The case cover is off right now though, so it could be some
EMI (heh, or an EMP from the recent trash on this list)  :-)

That's all I can think of ATM but for power from the utility company or
marginal power supply in the unit.

You shouldn't need to bother since RHEL 5 has yum. Just add your repo
definitions into your /etc/yum.repos.d directory.

The only limitation I have been able to see with RHEL's yum is the lack of
the priorities plugin. You can use protectbase as a replacement. If I get a
chance today, maybe I'll try to update that wiki page.

Have you spoken to the Panda people? Have you tried getting 
an rpm version. Have you looked in the 3rd party repos? There
is a reason for using an rpm-based distro rather than Slackware.

Re: [CentOS] changing partition priority on install

[Phil Schaffner]

Monty Shinn wrote:
...

Phil,

Thanks for your input.  I did find the location of the grub install 
modification.  Strange thing is, when I restarted the install, grub 
defaulted to the MBR of /dev/sdb.  I did not change any hardware or bios 
settings in between attempts.  I have no idea why the change happened.


Once the install was completed, the OS partition showed up as /dev/sda, 
even though it showed up as /dev/sdb during the installation process. 
Grub is apparently happily residing in the MBR of /dev/sda.  Again, I 
can't explain it.


If you (or anyone else) has insights to this behaviour, or can point me 
to where I can read up on it, I would appreciate it.


Thanks again for all your help.



Monty,

Not much helpful to add, except that I have seen many cases over many 
years of using RH/RHEL/FC and derived distros of device ordering 
changing among installer/boot/runtime versions of GRUB,  among 
installer/installed/updated kernels, as well as among different 
contemporary distros.  PCI slot priority, initrd, modprobe.conf, and 
BIOS settings are also variables so interactions among all these 
components can be quite complex.


If you really want to dig into it the kernel development and 
distro-devel mailing lists would be good starting places.  There are 
also old threads in CentOS and Fedora list archives, some of which I 
participated in, on these issues.  If you find any clear and 
enlightening docs on these problems, please share.


Cheers,
Phil

you are inserting multiple duplicate values somewhere where its not 
allowed. without looking at your schema it would be hard to work out 
what the issue is.


in other news, you dont need to dump + reload when you move from mysql-4

Thank you very much for the hint.  I went to the Mozilla Firefox Help page
and read up on this.  However, when I run:

# firefox -ProfileManager

All I get is a new Firefox window with all of the bookmarks and history of
my standard user profile.  Am I missing something here?

rsync or tar the /var/lib/mysql dir up and move that. I am guessing in

Alternatively if you did use complete-inserts in your dump, you can run 
the load with : mysql -f db_name < blah.sql ; then look at what lines 
the load breaks on and make sure the data looks sane in those lines.

If the initial condition is that no instances of Firefox is running then
"firefox -ProfileManager" will indeed bring up the Profile Manager and
allow one to chose which profile to use or manage profiles.  However, that
is the only circumstance where this occurs.  Once a Firefox instance is
running subsequent invocations skip the profile manager and start a new
window with the same profile as the first.

Is this intended behaviour?

MHR wrote:


The one problem I've seen and posted here was w.r.t. smartd error
reports showing 2^32 - 1 errors on one of the disks (probably my
system disk) every few minutes.  I thought this was more than just a
bit suspicious, since there are only 4,687,500,000 sectors on a 300GB
disk, and the likelihood of having errors on 4,294,967,295 (~92%) of
them is rather slim unless the whole system is crashing a lot (it's
not).  It's a Seagate 300GB, so I ran Seagate's SeaTools on it in
lightweight mode, and no problems were reported, which is good because
the disk is only about a year and a half old and has my CentOS root,
swap, boot and home partitions on it.


Precisely what error counters are alarming you?  If these are the
raw numbers for Raw_Read_Error_Rate, Hardware_ECC_Recovered, and
Seek_Error_Rate, it is normal for Seagate drives.  Look at the
normalized values for these attributes.  As long as they are not
approaching their failure thresholds, the drive is OK.  For further
reassurance you can run the SMART long offline tests ("smartctl -t
long /dev/whatever" -- see smartctl manpage for details) on the
drive.

You need to understand something about modern drives.  In the past,
drives achieved the first level of redundancy by recording each bit
in a large enough area to include many magnetic domains.  If some
percentage of the domains failed to hold the data (a highly likely
situation), that was OK because the read head would get enough
signal from the rest of the domains so that the bit would be
detected correctly.  Fast forward to today.  That multi-domain
redundancy is all but gone, having been replaced by more advanced
error correcting codes implemented in hardware.  Seagate has elected
to have the raw number for Raw_Read_Error_Rate report each instance
of sectors needing this level of correction and let the normalized
values reflect whether these corrections are occurring at a rate
higher than expected.

A similar situation exists for Seek_Error_Rate.  When a drive
performs a seek, there is a trade-off between speed and accuracy.
You can make it more likely that the heads go directly to the right
track by moving them more slowly and allowing more settling time.
Performance can be improved significantly by moving the heads more
abruptly and accepting that some percentage of the time a subsequent
small adjustment will be needed to get to the right track.  Again,
it is the normalized value for Seek_Error_Rate that reports whether
these adjustments are becoming necessary more often than expected.

Another data point.  I have a valid RHN login but with all entitlements

From past experience IIRC, if one tries to create a new account it must 
use a new email address, otherwise an error is returned about the 
address already being in use.


Also, if attempting a new registration, from:

But make sure mysqld is not running on either box when doing it this way.
Also, if you have any innodb tables you must have the exact same innodb

This is a known issue with Dazuko.  You can find some hint/solution in

Although it was with CentOS-4, the same solution should be applicable

Would be so much nicer if Red Hat also realised this [1] and made 
some

of those beta isos public.


I was really looking forward to testing this but when my download
completes in 3 hours I might have forgotten about it completely.

I'm too used to 10MB/s local mirror speeds :/


Bringing down the barrier for people to test and report problems for 
RHEL
Betas is something we have to discuss together with Red Hat. I 
discussed

some of my wishes in an earlier blog post:

http://dag.wieers.com/blog/rhel-beta-test-sig

but the dialogue has not taken place yet.

I think this is one of those very profound win-win situations that 
we have

to take advantage of.


As per the suggestion on Dag's blog i would be very happy to
participate in any sort of beta for 5.3. I don't have a RHN
subscription so my ability to get hold of the iso is limited but there
are a couple of features in 5.3 that would be of use for my company's
current projects
- so much so that we may be delaying a proposed roll out for them


Ok, what may not have been obvious from my mail (and I will make sure 
I fix that next announcement) is that anyone should be able to 
register on RHN for downloading these Betas.


So you do not have to be a customer to get an RHN account.



If there was to be any sort of CentOS based testing effort then i
would like to throw my hat (and a dell 2950III) into the ring


Well, you could become part of this effort. I would like to create one 
or more pages on the Wiki just for this purpose. We could allow people 
to write down what they tested, on what hardware and the items that 
failed. And in case they made any bugreports, we could link them on 
the same wiki-page.


The aim obviously is to report as much to Red Hat as possible, but 
also to record what problems others could verify in helping those 
reports. The other aim is to make sure we have a good idea of what 
problems we can expect in the upcoming CentOS 5.3 for the release notes.


What kernel version is in 5.3? Still 2.6.18?

there is an IPsec patch now in 2.6.27, BEET mode for ESP.

I need this mode for HIP in kernel mode, and have yet to successfully 
patch the kernel myself (the HIPL team does supply a BEET patch for the 
2.6.18 kernel, but...).


So I do not have a RH account. I suspect corporate does, but I am too 
distant from them to get access.


how might I go about getting attention on the BEET ESP mode?

This works.  Thank you.  The magical invocation is:

Edit ~/.bashrc or /etc/bashrc and add:

# Force Mozilla (Firefox) to prompt for profiles
# and start as separate instances for each.
MOZ_NO_REMOTE=1; export MOZ_NO_REMOTE
# Then invoke via "firefox -SelectProfile %u"

Log out and restart the desktop to get the changes to take effect for the
panel and menus. Changes made to ~/.bashrc or /etc/bashrc are picked up
with each new terminal window opened and do not require a logout or source
command if you invoke Firefox from the command line instead.

Many thanks. Now I can lose myself in the madness of model-model, view,

Theoretically true, but if you ask MySQL.com support they'll tell you
that a dump and restore is advisable.  It all depends on which
features you were using.  As just one example, if you were relying on
some of the previous auto-update semantics of timestamp columns,
you'll need to alter all the corresponding table definitions manually;
the upgrade process won't do it.

[CentOS] [OT] List of all email users

[Jussi Hirvi]

This is not CentOS-specific, hence OT.

I need a list of all email users on my system (there are hundreds of them).
The list could be extracted from /etc/aliases and the virtusertable.

Does anyone know of a script that would do this automatically? It would have
to 
- exclude commented-out lines (of course)
- exclude duplicates
- produce a list of usernames (or maybe unresolved email addresses for some
users) separated by a comma

I imagine perl would be the way to go. I haven't used perl at all myself.

Jussi

Hi Dag
according to RHN the only software that i can download is redhat
7.1,7.2,7.3 and 9

Without paying for a subscription for a machine i get

"No images were found matching your criteria"

So registering is free but entitlement isn't.

This was tried with both a corporate and personal login for RHN.

I guess i'll have to wait until a public release.

best wishes

Kevin: I suggest you try the CentOS 5.2 Live CD on it, after you

way you want it to, consider running Fedora or Ubuntu or something

will work on the HW you have.


Very good advice!

way to upgrade CentOS to KDE4 ?


If you upgrade to something that is not supported by the distro, you

Would not expect to see KDE4 supported before RHEL6/CentOS6.  If you

You can download and install, however, in order to

yum update

or even:

yum install something

you have to register the system on one of your available

virtusertable) should be prepared first - the list will include unwanted
users like "bin" or "mysql", mailing list name defined in virtusertable, and
possibly other strange things too.

I'm not 100% sure Robert, but I think this might be the kernel that

You could download it from here and at least take a look at what's in

And (I forgot to say that) - it weeds out users with a ":" in their mail

Agreed, but because of the way the rhn plugin works in yum, you can't assign
a priority to it. Apparently they've modified the plugin to set protect=1 on
RHN channels, so if you add other repos and don't want core system packages
replaced, set protect=0 and enable protectbase.

The only thing I can add is since you have 2 different families of 3ware
cards, one is using the 3w-9xxx driver and the other is using the 3w-
driver. Whichever driver that loads first will determine which card
initializes first.  First array gets /dev/sda. I think there are ways to force
a driver to load first, you have to adjust the alias scsi_hostadapter lines in
/etc/modprobe.conf in the order you want them to load like;

alias scsi_hostadapter 3w-
alias scsi_hostadapter1 3w-9xxx

and then make a new initrd.

Since yours seems ok now, this is for posterity.

The characters look binary, so this might be a problem of conversion
latin1 -> utf8 or vice versa.

Try dumping with:

mysqldump --default-character-set=binary ... >/path/to/dumpfile

And loading the dump with:

Let us know if that works.

[CentOS] VMWare Sandbox

[Thom Paine]

I need to experiment with ldap for a site I manage, and wondered if
vmware would be a good way to go for some testing.

My current server is RHEL3, which is getting dated, and I think that I
should refresh this server entirely in the move to ldap.
We need to have an ldap server for publishing email addresses for a
VPN for a nursing home that the upstream can harvest and we can browse
to send confidential patient records.

RHEL3 prollie won't cut it, so I'm considering moving to CentOS5.

If I get a nice working test environment working, I wondered about
running the server on VMWare, because the hardware will likely need to
be refreshed in 2 years anyways. Copying the vmware file and the data
to a new server would make for a fast upgrade.

Any feedback on what I am attempting to do here? Any other
recommendations on how I should tackle this?

Currently I'm using Samba 3 with passdb. It's nothing fancy, but it works.
We have about 20 XP machines here.

The server also hosts mail as well.

Closest kernel boot parameter seems to be the netdev= option.  Could 
perhaps use it with the dummy.ko device - don't know the details of how 
that would work.

Should work if you can afford the performance hit of VMware overhead.

We were thinking along similar lines and turned off caching. We also
added the drupal 'devel' module. It can be set up to show all the DB
calls a page is making. So far some slow queries, but nowhere near
explaining the whole 10-12s.

So far I've been able to rule out apache, php rendering, and DNS. It's
almost definitely a MySQL connection issue, and I'm reasonably certain
it's a php-mysql issue. Interestingly we've copied over the drupal
install to Fedora 8 and Fedora 9 boxes and it runs like a champ. I've
got a basic Drupal 6.5 install on my desktop (CentOS 5.2 x86_64) and
it runs well. I'm in the process of installing CentOS 5.2 on another
ESX VM to see if "something" was installed wrong, etc. Not ruling out
operator error here.

Nice to meet you as well, Dave. There certainly are a few of us
floating around.

$ mount -l
server001a:/vol01/home on /home type nfs
(rw,context="user_u:object_r:user_home_dir_t:s0",addr=10.1.1.11)


Shouldn't the users be set to user_u:object_r:user_home_dir_t?  I feel
like I am missing something simple...

I don't see any avc or related syslog messages and the nfs server is an
older netapp if that matters.

You can use either VMware Server 2.0 or VMware VI3i, provided your  
hardware is supported.


VMware Server needs some OS as base (CentOS5 should do well), but 3i  
goes on the bare metal - it's based on RHEL, too, though.

4 GB of RAM is the absolute minimum.
I wouldn't virtualize all storage. Use a separate server and NFS mount  
all storage from that, if you can (maybe Samba is the exception - SMB- 
exporting NFS-mounted stuff makes Samba even more tricky than it  
already is).
But the less disk-I/O you've got to virtualize, the higher the overall  
performance you can yield.
You can virtualize mail, but only if it doesn't do much I/O. Else it  
will be painfully slow.

What's your storage?
How do you plan to backup stuff?

CentOS is not officially supported by VMware (probably never will).
If you have a problem, you're on your own.
And VMware is not open-source.

But I'm not sure if there's actually anyting in the market that is  
better than VMware (for full virtualization).

[CentOS] Tired of Fedora, shopping for a new OS. Upgrade from F8 ? CentOS kernel versions ?

[Linuxguy123]

I've been a RH/Fedora guy since the RH8 days.  When Fedora came along, I
moved to it, but its been a bit painful beta testing software all the
time.   I ran Ubuntu for a while, but I found their package management
to be difficult... I do a lot of technical work, development and loading
and building special stuff.  I much prefer RPMs over other methods of
package distribution.

Presently I'm miffed with the Fedora community.  Back in July I blindly
upgraded to F9 because I was in need of a few things that it shipped
with.  Little did I know it contained KDE4 or more precisely a rough,
unfinished version of KDE4.  I stuck with it, however, and upgraded to
KDE4.1 and finally to KDE 4.1.2.

About a month ago I received a new laptop.  Being it was a new machine,
I did a fresh install of F8 on it, thus dumping KDE4.

While all has been well since then, I am watching the KDE4 release
schedule and noting that I don't think KDE4 is going to be done, ie
polished and ready to use until late spring, 2009.  I've also noted the
Fedora is going to abandon support for F8 before Christmas.  As F9
contains a very bleeding edge version of KDE4, I am loathe to upgrade to
it.   

Thus I am shopping for a new OS to solve this problem and the problem of
continually being a beta tester if one is an up to date Fedora user.
With Fedora it seems that one just gets a new installation working
nicely when support for it is dropped and the cycle starts all over
again.  I'd like to get away from that.

So... questions.

a) I am running F8 right now.   Most, but not all, of the package
versions seem about the same as CentOS 5.2.   Kernels are the notable
exception to this rule.  Could I forego F8 updates for a while, to leave
CentOS catch up, and then add the CentOS repository to my repo list and
"update" to the CentOS via yum ?

b) One of the things I really need are up to date (bleeding edge)
kernels.  For example, F8 has 2.6.26 kernels, whereas CentOS appears to
be running 2.6.18 kernels.  I do know how to build my own kernels, but
that is a pain.

Does someone keep a separate repository that has more modern kernels ?
Can yum be configured to use only specific packages (ie kernels) from a
specific repository ?

c) Is there any problem with using the livna repository for various
things that I might need ?  I notice that they don't have a CentOS
specific repository, but would it be OK to point to F8 or so and use
those RPMs ?

Thanks

I'm listening if you have any other comments or advice on my situation. 

LG

Check the distro hardware support pages.
Wireless?
Other hardware like graphics chips?

New laptops tend to have new hardware -- F9 or even F10 may be necessary
to get rolling with a minimum of effort on new hardware.   I tend to work
with install media that is about 6 months newer than my hardware based
on the assumption that most issues have been resolved.  With this in mind
enough works well enough that I can fix the remaining bits.   I have had
to resort to text mode install, USB ethernet hubs, kickstart tricks and more
when I stray and get too ambitious.

As Scott wrote... try a live CD that may be the fastest way to discover 
the issues.

It would not work too well.  For stability you would be better
installing CentOS-5 as the glibc, etc in F-8 are much newer than EL-5.

CentOS is a bug-for-bug rebuild of Red Hat Enterprise Linux. RHEL-5
will always be 2.6.18 so this does not look this would be a good
match. Using bleeding edge kernels on CentOS-5 are up to the user to
build and debug. Not sure how many applications you would have to
update to work with a bleeding edge kernel: udev, hal, dbus, etc would
all need updates and the programs relying on them would need
updates... recurse until you run out of packages.

No.. you would need to use EL-5 repository.

Actually, CentOS 5 branched from Fedora 6. At that point they did a freeze on
changes to the OS.

What do you need in the bleeding edge kernels? If you are looking at security
updates, those get backported very regularly. If you are looking for drivers,
that is a different story. The Enterprise distros tend to stay at the dull
side of the knife. The bleeding edge is not where you want to be when you want
a server up for "five nines".

There is only a problem if you don't mind breaking it. CentOS 5 was based on
Fedora 6. Fedora 8 is way ahead.  If you want something newer, CentOS 6 might
be out in mid-2009. It is speculated to be based on Fedora 10 or so, but I'm
sure that RedHat will make it as stable as possible. After all, the more paid
support contracts that you "don't" have to actually fix anything, the bigger
your profits are.

You can try the live cd of CentOS 5 and see if it works with your lappy.

You can have stability, or bleeding edge, but usually not both.
It is like asking for a car that runs like a Ferrari, but uses gasoline like a
Prius. You have to make choices.

That is not true, there are plenty of changes to the kernel, including 
rebases's, updates, fix's and even new packages being added in and 
obsolete ones being removed.


CentOS-5 today has little in functional terms common to fedora6. There 
are still some leaf nodes from those days, but saying something like 
'freeze on changes to the OS' is just wrong.

That would not be a bad idea. I always wondered how well a recent kernel

Let me add that nothing should be holding you (anyone) from starting a 
project by sending an email with intentions, get hold of a wiki-page to 
list your ideas and progress and motivating people to help and test.


Whether that is a bleeding-edge kernel project, a new tool to migrate 
sideways to and from RHEL, or a design, documentation or translation 
project. I am sure your effort is useful, but often it needs commitment 
and determination to get things going.

IMHO should be a separate repo, or at least a naming scheme that would
let people still use the "traditional" centos-plus kernels (derived from
the same kernel versions with additional components being turned on)
would be required.  Otherwise there would be too much risk of people
unintentionally updating to bleeding-edge kernels.

Along these lines, it might be a good idea to add some of the other more
"modern" features for those who want them and understand the risks -
again in a clearly specified bleeding-edge repo (or repos) - as long as
people are willing to step up and help with building, testing, and
maintaining packages.  From recent requests on the list there seems to
be some pent-up demand for newer features.  This could help establish
CentOS as both a platform that can be used by those who want EL
stability but don't need the support, and as a "bridge" for testing new
features on a stable base.

I think it would need to be a seperate repo for other reasons... I
believe lots of userspace/kernelspace changed in the 2.6.22 time frame
so a lot of sub-packages need to handle to.

ESX is not based on linux at all. ESX(not ESXi) includes
a service console that is based off of RHEL-3 though
that is for management only, virtualization runs entirely
within the hypervisor which is transparent to the user.

There is also a linux compatibility layer I believe for
drivers.

ESXi did away with the service console concept almost
entirely.

I've always been curious, in ESX, what manages the physical IO devices, 
what provides the actual hardware drivers for things like fiberchannel

does ESX have all its own direct hardware support?

Hello,

Just in case anyone wants to follow my original problem in the future, I
resolved my no swap problem according to Nate's advice as follows:

1. Confirmed that /dev/VolGroup00/swap was not in use by the system
2. Ran the following commands:
mkswap /dev/VolGroup00/swap
swapon /dev/VolGroup00/swap
3. Added the following to fstab:
/dev/VolGroup00/swap swapswapdefaults
 0 0

Swap partition now showing as follows, using 'free':
