All ServeRAID adapters from IBM are real hardware-based RAID cards.
The only exception are some cards then end with "e" in their name. But
all "ServerRAID Xi" cards are real HW RAID. Anyway, see here
"http://www.redbooks.ibm.com/abstracts/tips0054.html"; for a complete
overview of all IBM ServeRAID cards.

I've run a lot of machines with these type of ServeRAIDs and they all
worked fine.

[CentOS] I need help with CentOS installation on a Core 2 Duo Laptop

[Sadaruwan Samaraweera]

Hi,

 I've tried to install CentOS 5.2 on Core 2 Duo T5750 2.0Ghz laptop
but what happens is every thing hangs up when anconda system installer
starts. So I tried PCLinuxOS in it's text-based installer it detects
the CPU core 1 and when it try to detected the other one system gets
stuck. I tried these same two distro's  on another PC that have a AMD
X2 CPU on this PC I didn't had that problem everything went smoothly.

Thank you

[CentOS] Migration from VMWare to HP Blade

[Matthew Walster]

Hi all,
A few months ago, I migrated some of our internal servers to HP blades, as
the VMWare box they were previously running on was getting too slow.

However, it wasn't without it's problems, and eventually the only way I
could get them to work was:

Install the same version of CentOS on the blade (believed to be 5.0, but
/etc/redhat-release says 5.2)
Took down both servers, booting them off the SystemRescueCD, mounting all
the partition on /mnt/transfer etc
Ran rsync to copy all the data from one to the other - except /boot and
/lib/modules
Brought the blade up, and saw that it booted fine.

However, a new kernel has been released and we tried rebooting... And it
panicked. It seems to be LVM related, in that it can't mount /dev/root - and
I've tried manually running mkinitrd to regenerate the initrd to no avail.

I was just wondering if anyone had encountered similar problems, and knew of
any solutions?

I'm from a debian background, so am a little unused to certain aspects -
when a yum upgrade installs a new kernel, where does it pull the information
for boot from? A configuration stanza from within grub's menu.lst?

Regards,



Matthew Walster

Try installing with "linux acpi=off" (as the kernel command line for
syslinux).

The kernel which gets installed should be able to handle the system
after installation, the installer kernel sometimes has a few problems.

You seem to have the rpmforge repository installed, because the package
in the base repositories is called perl-DBD-MySQL (note the mixed case
MySQL). 

You should use the priorities plugin to clear that up. And you need to
exclude perl-DBD-mysql from the rpmforge repository, as the priorities
plugin seems to be case sensitive.

More information on Priorities:

Also the following option might be necessary: pci=nommconf

That is, for example
linux acpi=off pci=nommconf

Is there something special that needs to be done to enable ipmitool? lsmod

Yes, I did place rpmforge, mirrors.rpmforge, rhel-mondo, and rpmforge in 
the repos.  I had not installed the protect base or the priorities at 
the time of the intitial update.  Just now, I ran update with the other 
repos disabled and got about 5 libraries updated.  Now, what is the fix 
to update the rest of the things that amount to about 30 or so 
packages?  I will get the priorities and protect base before running any 
further updates.

We did not do anything. It is a bug in the priorities plugin.

The reason we have a perl-DBD-mysql is because that is the upstream name 
and the naming convention dictates to use the upstream name. That is the 
only reliable way for not having RPM clashes.


Maybe someone should report to Red Hat that perl-DBD-MySQL has a packaging 
bug ?

I've installed RHEL 4 on several IBM eSeries servers with ServeRaid
controllers and I despise them.  They fail too often and often don't
tell you that they are having problems until it is too late.  My
suggestion is to use Linux software for your RAID array, and bypass the
ServeRaid controller entirely.
  

Are you referring to the SATA controllers or to the SCSI ones?

I think you will find that in /boot/grub/grub.conf

[CentOS] kmod-kvm

[Jamie Wilch]

I use qemu-kvm on a Centos 5.2 server to run Windows XP virtually.
Usually a new kmod-kvm packages is released shortly after a kernel
update, and yum updates them both very nicely.  However, two new kernel
updates have been released now without a kmod-kvm update.  Does anyone
know if this package is still being supported?

Thanks

[CentOS] Clean serial console setup when using an USB to serial converter

[David Knecht]

Hello all,

I'd like to connect to a CentOS 5.2 system's console through a 
null-modem cable. An USB to serial converter is connected to that 
system's USB port.


When using this configuration statement in "/etc/inittab"...

...
# Run gettys on serial line (that is, a serial line connected to USB0)
usb0:12345:respawn:/sbin/agetty -L ttyUSB0 9600 vt100
...

...I get these messages if (and only if) the converter is *not* 
connected to the system (thus, if no ttyUSB0 device has been dynamically 
created):


Nov 18 15:58:41 anyvizor init: Id "usb0" respawning too fast: disabled 
for 5 minutes
Nov 18 16:05:22 anyvizor init: Id "usb0" respawning too fast: disabled 
for 5 minutes
Nov 18 16:12:03 anyvizor init: Id "usb0" respawning too fast: disabled 
for 5 minutes


Apart from that, connectivity to the serially attached console works 
fine of the serial line is connected.


Obviously, I would like to have a clean setup without any errors where 
this kind of console setup works like a charm.


As a workaround (since I did not get any further on an inittab-based 
solution), I tried to configure udev to spawn "/sbin/agetty -L ttyUSB0 
9600 vt100" once the converter gets connected. This is my udev 
configuration:


[EMAIL PROTECTED] rules.d]# pwd
/etc/udev/rules.d

[EMAIL PROTECTED] rules.d]# cat 10-custom.rules
BUS=="usb", KERNEL=="ttyUSB*" SYMLINK+="usb_attached_console"
SUBSYSTEM=="usb_device", ACTION=="add", 
RUN+="/etc/udev/scripts/respawn_usb_attached_console.sh"

[EMAIL PROTECTED] rules.d]#

[EMAIL PROTECTED] scripts]# pwd
/etc/udev/scripts

[EMAIL PROTECTED] scripts]# cat respawn_usb_attached_console.sh
#!/bin/env sh

getty_command_line="/sbin/agetty -L usb_attached_console 9600 vt100"

while [[ -e /dev/usb_attached_console && $(/usr/bin/pgrep -xf 
"${getty_command_line}" | /usr/bin/wc --lines) -eq 0 ]]

do
eval "${getty_command_line}"
done
[EMAIL PROTECTED] scripts]#

Again, connectivity to the serially attached console works fine once the 
system is up and running. However, the system does not pass the


Starting udev...

message displayed on the console (here, I mean the normal console 
screen, not the serially attached console) if (and only if) the USB to 
serial converter is connected when booting. The boot process continues 
fine once the converter gets disconnected.


Any hints for an inittab-based as well as an udev-based solution (or 
another concept to achieve the same result) is very welcome!


Thanks, David

What is the bug? It does not appear in the site you linked to.
It would be surprising if Red Hat are unaware of upstream changes 
as one would expect it to be rolled out into Fedora rawhide at least
even if the changes are backported int RHEL.

[CentOS] net-snmp puzzle

[drew einhorn]

I have a bunch of centos 5.2 boxes.

I'm trying to run smtp on all of them.
Using indentical net-snmp configuration files.
/etc/snmp/snmpd.conf

com2sec notConfigUser  localhost   smssnmp
com2sec notConfigUser  10.1.1.0/24 smssnmp

group   notConfigGroup v1   notConfigUser
group   notConfigGroup v2c   notConfigUser

viewsystemviewincluded   .1

access  notConfigGroup ""  any   noauthexact
systemview none none

syslocation SMS - North Carolina
syscontact [EMAIL PROTECTED]

pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat

I came up with this config file by tweaking some examples from howto
docs on the web,
I have not gotten to them point where I feel like I really understand
it as well as I should.

On some boxes it just works
On some boxes it complains with:

Nov 19 01:15:08 s1s0105 snmpd[7073]: /etc/snmp/snmpd.conf: line 1:
Error: bad source address
Nov 19 01:15:08 s1s0105 snmpd[7073]: net-snmp: 1 error(s) in config file(s)
Nov 19 01:15:08 s1s0105 snmpd[7073]: NET-SNMP version 5.3.1

But it works anyway.

On other boxes, it complains with:

Nov 19 10:55:03 s1s0106 snmpd[22621]: Warning: no access control
information configured.   It's unlikely this agent can serve any
useful purpose in this state.   Run "snmpconf -g basic_setup" to help
you configure the snmpd.conf file for this agent.
Nov 19 10:55:03 s1s0106 snmpd[22621]: NET-SNMP version 5.3.1

And does not work.  Fooling around with snmpconf leads to much
different config files but they don't work any better.

Any ideas?

And the other bug is in yum-priorities. It is not protecting base against

Ah! I just ran through this exact scenario a week ago. Turns out in
inspecting the anaconda code I couldn't actually find any support for
that directive, it looks to be more of a placeholder, but I'm no python
wizard. 

What is does support though is auto detecting and creating a simple
multipath.conf, good enough configure lvm with during the install.

This setup can be triggered by passing 'mpath' as a kernel parameter
during kickstart.

Only other thing I had to do was add a bit of %post scripting to tweak
multipath.conf and lvm.conf for our particular drive/controller setup.

I played with it for a couple hours and my experience was:

- It created the multipath configuration, though in %pre I had to
  run multipath to enable multipathing support
- It could then see the device but would not install to it, after
  creating a partition in my experience multipathing has to be
  restarted, so the only way I think to get it to work is to come
  up with a way to manually partition in %pre and then tell kickstart
  to use the pre-existing partitions after restarting multipathing
  in %pre. Quite a bit more work than I expected given the few notes
  I have seen saying that it should "work". Given my timetable I
  decided to give up on this for now and use internal disks, I can
  re-visit it again later.

VMWare ESX 3.5 works flawlessly when booting from SAN by contrast!

[CentOS] noauto option ignored in CentOS 5.1?

[nate]

I have worked quite a bit with CentOS 4.x with
SAN, multipathing, LVM etc. The way I mount my
file systems is using a script that is called during
startup that runs fsck, imports the physical volumes,
and volume groups, activates the logical volumes, creates
the mount point if needed then mounts the volume, I mainly
made it for software iSCSI due to the iscsi stack loading
after the system mount process. I adapted it to my fiber
channel systems as well and it worked great(mainly so
I could have a consistent experience between FC and
iSCSI).

In testing with CentOS 5.1 it seems that my entries
in /etc/fstab that are marked "noauto" are still infact
queried when the system boots (before multipathing, etc
fires up). These devices don't exist at the time which
causes the boot to halt(so I can fsck the file system
manually). I have worked around it by commenting out the
line in fstab, and just adjusting my script to look for
the commented line, but this never happened under
CentOS 4.x, seems like a bug ? I peeked at Red Hat's
bugzilla but didn't see much.

If so I can file one..

thanks

change default to 1 if that was your working kernel. If that doesn't help 
the problem is not what/where you think it is.

But was it necessary to obsolete perl-DBD-MySQL? The older versions (up to 
4.007) obviously didn't and there was no priorities problem until then 
(with 4.008). There was another package (I don't recall the name, python 
stuff?) that had the same problems recently. I agree that check_obsoletes 
should have been in the yum config in the first place, but on first glance 
and from my point of view as just being a user and not a packager the 
obsoletion seems to have been unnecessary.

[CentOS] qlogic driver not scanning scsi bus on load CentOS 5.1

[nate]

Very strange behavior, been banging my head against the
wall on this one too. It works fine on CentOS 4.6, the
behavior is when the driver loads the bus is not scanned
or at least the devices that are exported are not detected.
(they are detected in the HBA bios no problem). If I issue
the qlogic bus scan command it doesn't get anything back
either. If I manually add the devices with "scsi add-single-device"
they immediately pop up.

I am new to using FC on CentOS 5.x with 4.x it was so easy
perhaps I should just stick to what works.

Filing a support case with my vendors as well though not
sure how much help they'll end up being.

Running a "QLogic Corp. ISP2432-based 4Gb Fibre Channel to
PCI Express HBA". Tried both the drivers from qlogic's site
and the ones that ship with CentOS.  Once the devices are
detected everything works fine. Though I don't want to
hard code the "scsi add-single-device" commands into my
startup scripts if I can avoid it, rather use CentOS 4.6
instead.

Anyone seen this kind of behavior before?

thanks

[CentOS] L2ARC (disk caching) for Linux?

[Ray Van Dolson]

First off; are there any storage-centric mailing lists that target
Linux specifically?

Secondly, I'm wondering if there's anything in the works or already out
there similar to Sun's L2ARC[1] for ZFS.  Basically this is a
filesystem (or maybe lower-level) cache for reads, writes that can be
comprised of faster media like SSD.  I think it could make SATA-based
JBOD solutions a lot more attractive from a performance perspective.

Anything out there along these lines already or suggestions on a better
place to dig for information?

Hmm.. not sure about older versions of CentOS but for lvm over iscsi in
5.2 all you should need is 

/dev/foo.vg/foo.lv /foo xfs _netdev,noatime,rw 0 0

in /etc/fstab and iscsi node startup set to automatic (which is the
default I believe). _netdev being the key as it will mount it after
iscsi is loaded and connected. 

And since the volume is being asked to mount at boot time, the startup
scripts are smart enough to find and activate the volume group and
logical volume.

Nothing extra required. 

Only issue I've had is sometimes after unclean shutdowns the volume
group gets deactivated and must be manually activated and mounted,
though this has never prevented booting.

Though this doesn't include the fsck'ing you mentioned..

Having just done the opposite (test migrating a CentOS server from physical 
hardware to VMWare), I have a very good idea  :-)  It was CentOS 4, but the 
basic bits should be the same

You need to edit /etc/modprobe.conf, and change the line (or lines) that start 
with:
"alias scsi_hostadapter"

If the server was vmware, the existing lines are probably
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptscsih

I'm not sure what you'll have to change mptbase and mptscsih to be; on HP 
servers, cciss is the correct driver.  Others will vary (you could try a quick 
basic manual install on the target hardware and see what gets put in that file 
by the OS installer).

After you've changed modprobe.conf, re-run mkinitrd and reboot.  Should be good 
to go.  You'll also have to watch out for HWADDR in 
/etc/sysconfig/network-scripts/ifcfg-eth*, either changing it to match your new 
hardware, or removing it entirely.  Kudzu will probably take care of sorting 
out the network card driver entries in modprobe; follow your nose and take a 
guess, you'll probably get it right.  Either way, mkinitrd is only necessary 
(in this case) to get access to your root device

Hope that helps,

Yeah it does. multipathd is started by default just after iscsi so

Found the root issue here I believe in /etc/rc.sysinit

if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then
fsck -T -t noopts=_netdev -A $fsckoptions >
/etc/rhgb/temp/rhgb-console
else
fsck -T -t noopts=_netdev -A $fsckoptions
fi

It scans all file systems by default unless the _netdev option
is set, whereas in CentOS 4.x it ONLY scans the root file system

if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then
fsck -T -a $rootdev $fsckoptions > /etc/rhgb/temp/rhgb-console
else
initlog -c "fsck -T -a $rootdev $fsckoptions"
fi


I'll think about filing a bug/feature request I think the 'noauto'
option should be included in the exclusion list.

Perhaps fsck should be fixed as well, according to the manpage
'noauto' means it won't get mounted when you do mount -a, perhaps
it should not get fsck'd either if you do fsck -A

Matthew:  You're welcome. As Kai wrote earlier, you need to change the
line that says default=n to the "title" line for the kernel you want
to use (I think it defaults to 0, after a Kernel upgrade). Every time
you install a new kernel, it will change this file, so you may need to
go back and tweak it, after a kernel upgrade. Lanny

I have a problem with one of my machines, and have narrowed down that
it could either be the CPU, RAM or motherboard, but before I take it
back to the suppliers, I need to know what is wrong. They will switch
it on, and see that it works. But it's not taking the load that I
expect it could. In fact, it's not taking the same load as a machine
with a Intel E6750 Core 2 Duo & 4GB RAM. This server should be 2 - 4
times faster & handle 2 - 4 times the load of the E6750, yet it
doesn't and I need to know why. I don't appreciate being told that the
hardware I have if inferior.





Hi Rudy,

	John is a veteran on this list and you could probably learn many things 
from him.  I suggest you read:


http://www.mit.edu/~jcb/tact.html

(that could maybe explain why you seemed irritated by John!)

	By the way, server grade hardware is just that: Meant to serv and 
include specific features for that particular kind of job.  That doesn't 
mean that a workstation board won't be able to do a server job at all. 
Having said that, i manage servers since a long time and i can assure 
you that using serious server hardware with ECC translates in lower 
costs in the long run.


	Sure you can still have problems with server grade hardware!  But then, 
we could try to obtain statistics and MTBF to get a better idea.


	But i find ECC error indicator to be invaluable and there a many other 
features that will help to pinpoint problems rapidly.


	So Rudy, i can understand that you may have hardware problems and 
probably pressure to solve them but IMHO, it's just a classic example of 
TCO.  And i read that you had problems with Dell servers, then try 
something else!  It's OT but can say that i have many Tyan and HP 
servers in production and no problem at all.


Hope you'll solve your problem.

I believe, as a Consultant, one has a legal and moral obligation, to
give the client the best advice one can. If they do not go that route,
we've tried our best I've seen them go both ways.

Seems a little impertinent what our learned friend Steve Huff
has sent to me off-list in a huff :- 

- I was subscribed for a few days last month.
- Many of us don't do "just CentOS". We have other mailing lists
and OS's installed. We also happen to have lives as well to live.
- Even this month when I'm subscribed fulltime to the list, 
I don't read all messages on the list (nuff' said).
- What is posted on the list is "not Gospel". If something
affects all CentOS users, perhaps a prominent announcement
could be made on the website or somewhere.
- I'm sure there are issues other than the Debian Openssl
bug that affect all CentOS users.

John, I know what ECC does. I have 2 Dell PE860 servers with 8GB ECC
DDRII RAM as well, and they're both giving RAM problems. I had top
swap-out the RAM 2 times with the suppliers already, and swapped out a
motherboard on the one of the servers. Honestly, ECC isn't my
favourate to use.


Wow!  Everybody doing serious business wouldn't go without it (i work 
for a couple of Banks and government agencies), but that's your choice 
and i respect that.  But if you want to talk about five 9's, then you'd 
surely go with ECC and other invaluable features like watchdog timer, 
management cards, BIOS serial redirection, chip kill, etc.


It all depend on your needs i agree but don't reject server grade 
hardware so easily!




At the same time, I have about 8 servers with cheap Gigabyte
motherboards and non-ECC RAM, which have been running for close to 4
years now, without any hickups at all.


That's bad stats.  It's not because my neighbour has a problem with his 
Mercedes and that i have no problem with my 4 Hyundai that Hyundai are 
better than Mercedes!!!  Not only that, but sitting 6 adults in a mini 
Hyundai may be possible but we'll be much more confortable in the big 
Mercedes!  Know what i mean?




It's the first time I try the Intel board, since it's supposed to be a
step-up from the desktop boards, and has 4 memory slots as apposed to
only 2.


... and limited by the fanout of the CPU / Chipset... As you put more 
memory, you'll have to relax timing and use proper memory brand that is 
certified for the mainboard.



The server had the same problems when I only had 4GBM RAM (2 slots
used & 2 slots open), so I don't think that the capacitive load is the
problem here. Right now the server is still at the datacentre - which
is 2 hours drive there & back with traffic, so I'm going to get it
later today / tonight, as soon as I've moved all the data across to
the slower gigabyte server, and then I can try the RAM timings thing
in the BIOS.


This could be a chipset problem, bad power supply, and the list goes on.



But, how can I put a LOT of load onto it, and see what's causing the
problem? For all I know, the motherboard could be faulty, or the CPU,
or maybe even the SATA bus?



Putting high load without having hardware monitoring won't tell you much 
IMHO.


I'd first test the power supply.  Then remove everything you can and 
test with Memtest86+ (let's say, overnight, and while you're at it watch 
the power supply under load).


Swap memory with some you know is good.  If the problem persist, you 
could possibly have a chipset problem.



Good luck.

Are you rolling out your own patches for Samba? If so can

[CentOS] syslog remote computers

[Craig White]

Trying to figure out if there's a way to get syslog.conf to direct
remote logging from a wireless access point to log to a separate file
instead of the main syslog and can't figure out how that could be done
from man syslog.conf (or man 2/3 of syslog)

this clearly doesn't work

192.168.1.251.*   /var/log/WAP-2.log

which according to the man page, makes sense since this the IP address
is not a facility.

Is there a way to do this that I am missing?

I'm not 100% sure that you can do this with the stock syslogd. You might need
something like rsyslog to handle that.

The AP's syslog parms must match the syslog.conf parms.

e.g., for a MikroTik AP,

# MikroTik router messages

suggests that perhaps daemon.info would work, I dunno.  At any rate,

I gather that this means that it's facility is kernel and thus I can't
separate it from the local machine.

Not rolling out patches just trying out samba-vscan with clamav on a few

The stock syslog package can't do this. You need rsyslog to make this
happen. You can set up various templates and filters based on the log
file information also. See
http://www.bofh-hunter.com/2007/12/31/centralized-logging-with-centos-and-rsyslog/
for a brief walkthrough on the basics.

[CentOS] XFS or JFS on CentOS 5?

[Ray Van Dolson]

Hi folks... trying to pick between jfs and xfs for a filesystem.  In
the past we've used jfs with CentOS + centosplus, however, an older
post indicated that this may not be the best choice as the version of
jfs included with the centosplus kernel would only be as new as the
version that was included in the 2.6.18 kernel as RH doesn't backport
fixes...

It looks like xfs isn't part of the centosplus kernel, but instead is
provided as a kmod -- so I'm thinking it might be the better choice
based purely on the fact that it's likely to be current.  Is my
understanding correct there?

What would stop us from building a kmod-jfs against the latest jfs from
the up-upstream kernel and not building jfs.ko in the centosplus kernel
at all?  It looks like jfsutils is a fairly recent version...

Thanks,
Ray

[CentOS] CentOS/RHEL, PHP and zip archives

[David G. Miller]

I'm trying to get bulk photo uploads working with a Drupal web site.  
The person who coded the Drupal photos module I'm using decided to use a 
zip archive as a means of batching together a collection of picture 
files for a bulk upload.  Apache is reporting the following PHP error 
when the bulk upload feature is used:


[Sun Nov 16 22:05:38 2008] [error] [client 192.168.0.192] PHP Fatal 
error:  Class 'ZipArchive'
not found in 
/var/www/fraud/html/davesBlog/sites/all/modules/photos/photos.module on 
line 1375,

referer: http://davenjudy.org/davesBlog/node/39/photos

The PHP code at line 1375 in photos.module is an unremarkable 
instantiation of the zip archive handling object.  Some Google searches 
indicate that zip archive handling is a compile time option of PHP and 
lack of it would cause this error.  Running php -i tells me that the 
CentOS/RHEL PHP was not built with the --enable-zip configuration option.


Does anyone know of a way to get PHP to correctly handle zip archives 
short of rebuilding my PHP installation from the source RPM with 
--enable-zip as a configuration option?


Thanks,
Dave Miller

Thanks for the reply John.  However, my question wasn't so much "if I
should" but how the xfs support in CentOS compares to jfs.  It seems to
me that xfs is a bit more up-to-date.

If you'd like, consider the question academic vs giving me a
recommendation that pushes me down the path of unsupported filesystem
doom. :-)

I have not tried either of these on CentOS, but have on SuSE
Enterprise Linux.  I have lost data on both jfs and xfs on SuSE
so now use ext3 for everything as it's the only file system that
has never bitten me in the butt.

I've been using XFS on centos for a couple of years with no problems. 
Only minor annoyance was when the kmod for new kernels was slow to 
appear, but thats not a problem any more due to the non kernel version  
dependant kmods.

Which one to use seems to come down to what you're using that
particular filesystem for.  I'm using xfs with CentOS 5.2 on one of my
system's non-root filesystem.  Seems to work well.  I haven't used jfs
on CentOS in a while, but not for any of the reasons you've listed.
