[CentOS] Centos 5.7 - bridging firewall crash (only since the update) - dmesg output included - Trying to vfree() nonexistent vm area (ffffffff885d9000) ....

[Morgan Cox]

Hi.

We have several Centos 5 firewalls in our company  - they are all in
bridging mode.

We updated them to the latest Centos 5.x last night.

4 hours later there was a crash..  (previously it had never crashed - and
had been running for at least 1.5 yrs)

The crash occurred when someone added a rule, after rebooting it was fine  -
the thing is it can't have been a bad rule as the first thing the server
does is load the firewall (same) rules..

In /var/log/messages I can see:-


Oct 13 09:27:46 new kernel: Trying to vfree() nonexistent vm area

[CentOS] Using SD-card reader? (Lenovo T61/Richo R5C822 controller/sdhci driver)

[Toralf Lund]

Hi

I'm trying to access an SD-card using the built-in reader on a Lenovo 
T61 Laptop running CentOS 5.7. The unit is recognised by lspci:
# lspci
[ ... ]
15:00.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro 
Host Adapter (rev 21)
15:00.3 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 11)
15:00.4 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host 
Adapter (rev 11)
15:00.5 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 11)

and a driver is loaded and appears to find the device  - from 
/var/log/messages:

Oct 13 09:30:48 i58524 kernel: sdhci: Secure Digital Host Controller 
Interface driver, 0.12
Oct 13 09:30:48 i58524 kernel: sdhci: Copyright(c) Pierre Ossman
Oct 13 09:30:48 i58524 kernel: sdhci: SDHCI controller found at 
:15:00.2 [1180:0822] (rev 21)

GSI 18 (level, low) -> IRQ 225
Oct 13 09:30:48 i58524 kernel: mmc0: SDHCI at 0xf8101800 irq 225 DMA

But then what?? If I insert a card in the drive, nothing particular 
happens. I mean, I the status LED on the unit lights up briefly, but 
there is no automount or anything, and I get no messages in the system 
log. And I can't find any appropriate devices under /dev. The card is 
accessible when using WinXP on the same machine...

Help, anyone?

Re: [CentOS] Virtual host package, command line, I need help

[Bob Hoffman]

One of the mods requested some data, here ya go..think it is a video 
issue...

I think I am narrowing it down to choking on my ATI ES1000 
controller..which might be causing some issues.

When I did a full desktop, everything worked okay though, but command 
line only or with x windows system video is a complete no go.
although I can pull up text things like system-config-network, x will 
choke on config/hal: couldn't initialize context: (null) and pop right 
out. Display cannot open.

Its make sense because now and then my ipmi card just gets a blurry 
video image and I have to reset the card.
Also, it just shuts off (loses connection/video) sometimes and I must 
login again. Thought it was the card...but...
it only happens when I am installing linux or it is installed. If 
playing in bios it has never happened.

Tried the nomodeset thing, no change.

Re: [CentOS] Virtual host package, command line, I need help

[Christopher Hawker]

Sorry if I seem a bit dumb in this question, but are these virtual
servers going to be used in a production environment or are they test
servers? Also, in my experience, using a GUI on a server is not really
necessary, as everything can be done from the command line. Yes it may
be easier to do it with a GUI, but if you know what you are doing and
what to do it professionally, stick to using the  command line and
give the idea of using a desktop the flick.

Christopher Hawker

I do not want to use the desktop. I am in command line. It will not work. You 
cannot
install a guest (production server, not test) without some kind of installation 
walk through.
a text install, a vnc, sdl, whatever...it should be able to open a window to do 
so.

the only way I could get it to work was a full install of gnome and that is not 
workable.
so little online with KVM and centos6, most are xen.

For some reason the virt-viewer and anything else cannot access my video for 
some reason.
 From looking online, this is a common issue among command line 
virt-installs..but no one
ever posts a final solution..lol

So far, after a few weeks of this, I have been unable to install, via command 
line, one guest.
I cannot get any kind of installer to come up in any kind of window/gui/etc.

very frustrating. Just sitting here with my useless brick of a computer unable 
to deploy it.
Gonna call supermicro today and ask about the es1000.
Also will try to install xorg to get to the xorg.conf and see if that can help, 
however most
errors are deeper in the boot than xorg.
Gonna try playing with the devices in grub I guess too.
Was thinking of getting a second card and trying to see if that would work.

bugzilla had tons of people complaining about issues like this one...it is 
probably the es1000
choking the systemcan't think of anything else that would cause displays 
that try to start to
just die.

However, in full gnome, it works flawlessly...so that theory is a little off... 
Card must be working.
Must be a setting in the basic 'virtual host' package that needs fine tuning.

Stil more pain, esp. since they decided to drop system-config-display,
which would always get you at least a minimal working video.

May I strongly recommend yesterday's XKCD ? Talk

I am down to just a call to supermicro, which will probably be a waste.
After that I think buying a cheap 'more compatible' vga card for the box 
might solve the problems.
My last way out is to bite the bullet and install xorg/gnome/etc and 
hope it does not crash the guests.

Obviously centos 6 is pretty new, KVM is fairly new in a way (everyone 
does zen), its linux (),
and KVM googles don't work so well with KVM switches out there..lol

Not sure of the path here, I know continually reinstalling, repackaging, 
playing with grub, etc...cannot be
the way intended for a brand new install just to install a guest via 
command line.
I am thinking new video card.

First time sorely disappointed with supermicro...very disappointed 
unless they have a fix.

Have you tried adding another Ethernet adapter? This is because I was

So it might a driver issue, i.e. the VIA driver is not reporting the
link down correctly.

I have a similar controller in my Dell laptop:

http://wiki.centos.org/HowTos/Laptops/Dell/XPS_M1330

03:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro 
Host Adapter (rev 22)
03:01.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 12)
03:01.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host 
Adapter (rev 12)
03:01.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 12)

and at the time I tried it (a couple years back) the device was not 
supported on el5.

Originally I tried an updated driver from elrepo.org (IIRC it was 
kmod-mmc), which almost worked - I could access the device but I seem to 
recall I still had issues writing to it.

Eventually I installed an updated mainline kernel from elrepo.org 
(kernel-ml) and would boot to that kernel on the rare occasions I wanted 
to use the device which worked flawlessly. Elrepo.org currently offer 
2.6.35 and 2.6.39 series kernels for el5 and either should provide 
support for the device. If you want to try one I'd be tempted to 
recommend the kernel-ml-2.6.35 series.

http://elrepo.org/tiki/kernel-ml

I'm a bit disappointed to learn from your post that this hardware still 
isn't working natively on el5, although I suspect such issues receive 
very little attention/feedback on a more server orientated distribution.

Hope that helps.

[CentOS] pvresize on a cLVM

[Antonio da Silva Martins Junior]

Hi, 

   I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done 
it).

   On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it. 

   Has anybody done this on a cLVM PV ? 

   I'm trying to rescan the devices, but I can't "see" the new size. And,
googling on it I can only find RHEL5.2 responses.

   Thanks in advance,

 
   Antonio.

1. CentOS-virt mailinglist should be still active.

2. Are you aware that you can have one Desktop PC with installed 
Virt-Manager and use it to connect to running libvird (KVM) daemon on 
your server? I have KVM Guest on my C6 Desktop and use graphical 
Virt-Manager to setup new Guests. But, from that same Virt-Manager I am 
connected to my C5 server with C5 KVM Guest, and I can add new systems 
and manage existing ones.

3. Are you talking about actual VGD graphic card on the Barebone server 
(KVM Host)? If yes, do you know what type of Graphics card you have? 
ELRepo repository (www.elrepo.org) has newer drivers for ATI nVidia and 
Inter graphic cards.

Well, I did it :D

   After more search I found this: 
http://serverfault.com/questions/66638/how-to-extend-a-san-based-vdisk-in-red-hat-without-rebooting

   With this instructions:

1) Increase size of LUN in SAN
2) Check with "multipath -ll" which devices belong to said LUN
3) For each device above, do "echo 1 > /sys/block/sdX/device/rescan"
4) Go to multipath command line with "multipathd -k"
5) For each device, do "del path sdX", "add path sdX" while hoping that
  the multipathing functionality works as advertised and fails over 
properly.
6) "resize map multipath-map-name"
7) Exit multipath command line (Ctrl-D), check with "multipath -ll" that
  new size is seen.
8) pvresize, lvextend, resize2fs
9) Profit!

  Well, to do steps 4, 5 and 6 on a 10 node cluster will be a litte slow... 
then I did:

1) Increase size of LUN in SAN
2) Check with "multipath -ll" which devices belong to said LUN
3) For each device above, do "echo 1 > /sys/block/sdX/device/rescan" 
4) service multipathd restart
5) pvresize, lvextend, resize2fs

   The steps on 3, 4 and 5 where did with cexec (from C3 package).

   Works!! Solved!!

   Thanks,

 Antonio.

Re: [CentOS] Virtual host package, command line, I need help [solved, sort of]

[Bob Hoffman]

The thread is about an issue of not being able to bring up simple guis 
required to
install virt guests on centos 6.

Apparently a bug exists in xorg-x11-drv-ati-6.13.0-6.el6-x86_64
the driver for the ati es1000 and how it deals with xorg.
Ubuntu I think has popped in a fix as well as many others.
Redhat, as far as I could tell, added it to 6.1..something I guess not 
coming to centos for a while.

it is having an issue of addressing two things at once and freaks itself 
out. Simple fix (for the devs i guess) and listed
on the freedesktop.org bug list. However I have no idea how to redo a 
driver like that, much less specifically
designed for redhat.

After a month of fighting this and finally figuring it out, kinda bummed 
I cannot resolve it.
I have no choice but to buy a temporary card, lose access to IPMI due to 
second card, and just hope
they get out 6.1 sometime soon.

If you are getting a board and not doing gnome/kde but want to do 
X...you may have an issue if
it has an es1000, ati, radeon rn50.

well...now off to find a dang card so I can actually deploy this thing.

sad.

Can you not just pull that package from SL 6.1, or rebuild the SRPM from
Redhat?

As others have pointed out, a GUI is unnecessary and also a bad idea on a
KVM server.

You'll want to have an account remote into the KVM server that isn't root.
 Use PolicyKit to add a group or user to have rights to control libvirt.
 Then you can either run virt-manager on a Linux desktop to connect to KVM,
or use X11 forwarding via SSH to view the server's virt-manager remotely,
which still won't require a desktop environment to be installed.  I have the
process and details documented here,
http://itscblog.tamu.edu/startup-guide-for-kvm-on-centos-6/.

Hope that helps,

There's really not much you need to install.  Minimal install + xauth + gedit
and I'd have thought you were there.  xauth is the important bit that you can
accidentally miss off.  You just need to check for ssh X forwarding working.
ssh -Y to your server and "echo $DISPLAY".  If it's not defined, you've got a
problem.

jh

I finally got it to work. I think the error was the lack of vfb=[] object 
during the
initial install. If you have a vfb from the beginning it will work.

I ended up with 267 packages in less than 900MB and all my goals were met:

  ++X11 forwarding works in ssh without an X server install

  ++geany works over ssh

http://paste.ubuntu.com/707751/

next I want to compile a C6 kernel that supports nfs root.
