Tg3

2009-07-27T05:48:29Z

Ericgearhart:

This is the error I see when trying to boot a server with a Broadcom tg3 NIC:

<pre>[ 6.637970] tg3 0000:02:02.0: PME# disabled</pre>

Very similar to the post [http://lkml.indiana.edu/hypermail/linux/kernel/0903.3/00195.html here] on the LKML

Also I cannot even 'ifconfig eth0 up' - I get "Device or resource busy." The NIC won't even come up at all booted into FOG debug mode)

Rolling back to kernel 2.6.28's bzImage (see [http://sourceforge.net/projects/freeghost/files/Kernels/Kernel-2.6.28.7.PS/download here]) got this working for me. -[[User:Ericgearhart|Ericgearhart]] 22:48, 26 July 2009 (MST)

Dell PowerEdge R200

Ericgearhart:

For this server several things have to be done to FOG for image upload and image deploy to work

*Kernel 2.6.29 (included in FOG .26) apparently has a bug in its tg3 driver. See [[tg3]] for details on the kernel to downgrade back to

*On image deploy, I had to edit FOG's init.gz (see [[Modifying the Init Image]] for details) and add a "-m" option to the deploy section where partimage is called (edit bin/fog and scroll down towards the end of the script). <br /> For some reason, when the R200 PXE boots, it mounts the PXE filsystem root (init.gz) on /dev/sdb3, but also the drives to image to appear as /dev/sdb and /dev/sdc. Partimage thinks that the filesystem it's about to drop an image on is already mounted. Adding '-m' tells Partimage to not care if the filesystem is already mounted.

After these two tweaks I am able to image and deploy to about 20 R200 servers (running CentOS and RHEL version 5.3)

Ericgearhart: PowerEdge R200 moved to Dell PowerEdge R200: Name makes more sense

Partition checks found error(s) on partitions

2009-07-08T02:19:11Z

Ericgearhart:

*Here is my initial problem:
<pre>
Error from Partimage: "Partition checks found error(s) on partitions" (Clonezilla works fine on this box though...)
Here's my filesystem layout:
/dev/hda1 is /boot
/dev/hda2 is swap
/dev/hda3 is /

An 'fsck -f /' reports no errors when I boot into single user mode,
and the box boots cleanly, yet when I setup a task to image the box in
FOG I get this error when Partimage tries to image the / filesystem.
The box is RHEL 5.3, if that makes a difference. No LVM in use, just
plain ol ext3.

Even stranger is the fact that Clonezilla (which also uses Partimage)
images and restores to the box fine
</pre>

'''I was able to resolve this error when I saw this post over on the FOG forums:'''

"RE: FOG 0.26 backup of Centos partition fails By: Tom Merrick
(tmerrick) - 2009-03-14 05:00

One way around this is to put a -m on the partimage command line,
telling it to ignore if already mounted.

Also, I wonder if there should not be a -M on this line also so it
will not save the MBR since you save it first anyway.

One note though is that people should specify linux as the OS type if
grub is the boot loader, even on dual boot systems. "
</pre>

'''NOTE THIS IS FOR FOG VERSION .26 - they might incorporate this fix into .27'''

<pre>
cd /tftpboot/fog/images
gunzip init.gz
mkdir initmountdir
mount -o loop init initmountdir
cd initmountdir/bin
nano -w fog
</pre>

Page down to line 772 and add '-m -M' to the end of it
The line should looks like this when you're done:

<pre>/usr/local/sbin/partimage save $part $imgpart --volume=9900000000 -z1 -o -d -f3 -b -c -m -M</pre>

Page down to line 851 and add 'm -M' to that line as well

When you're done line 851 should also look like this:
<pre>/usr/local/sbin/partimage save $part $imgpart --volume=9900000000 -z1 -o -d -f3 -b -c -m -M</pre>

After editing these lines, we have to cleanup and put init.gz back where it was:

<pre>
cd ../..
umount initmountdir/
rmdir initmountdir
gzip init
</pre>

A task to image your CentOS / RHEL host should work now... that fixed it for me! [[User:Ericgearhart|Ericgearhart]] 19:17, 7 July 2009 (MST)

Graphical Menu

Ericgearhart: Updating the links and instructions

'''This is a quick guide to replacing the default boot prompt with a graphical menu.'''

''As of FOG 0.20 the included pxelinux.0 version is 3.71''

The prep work:
<pre>
Create your backups first:
cd /tftpboot/
cp -p pxelinux.0 pxelinux.0.bak
cd /tftpboot/pxelinux.cfg/
cp -p default default.bak

Grab a more recent version of syslinux:

wget http://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-3.82.tar.gz
tar -zxvf syslinux-3.82.tar.gz
cd syslinux-3.82
cp com32/menu/vesamenu.c32 /tftpboot/fog/
cp core/pxelinux.0 /tftpboot/

Edit a new file called default, make the menu and save it.
cp default /tftpboot/pxelinux.cfg/
</pre>

Tips:
Always make a backup and test your work.
If you get a completely blank screen make sure you have a pxelinux.0 and vesamenu.c32 from the same distribution of syslinux.
