Can't mount local disk

weisstik — Tue, 01 Jul 2008 17:31:45 GMT

Hello together,

i have a problem concerning the mount process at startup.

My system, a RHEL 4 update 5 box, is installed on SAN disks. I have installed a Smart Array controller and added a few disks.

When the server starts up it always returns an error concerning the smart array volume group.

I have uncommented the "wrong" entry in the fstab file and the server starts up fine.

I had to activate the volume group manually

vgchange -a y volumegrp_name

After that I was able to mount the filesystem without any problems.

Does anybody know if it takes longer to mount or activate the VG's on the smart array? I guess that the error occurs due to this configuration.

Thank you in advance.

Shalom,

First lets slowly diagnose the problem.

fdisk -l

What do you see? Is something missing.

Quick solution:
You may need to do a new ramdisk image mkinitrd due to an LVM bug in this version of Red Hat Linux.

Did you define a volume_list in /etc/lvm/lvm.conf?

Hello,

no, I havent defined a volume list and the partition is available.

If I mentioned before, I have no problems to mount the filesystem after startup.

At the startup the volume group isn't activated and so the mount process fails.

Thanks.

If I'm reading your post correctly, you were originally booting from SAN and then installed a Smart Array controller. If this is the case, then your initrd image probably doen't have the cciss driver needed for the Smart Array controller during boot.

Create a new initrd image that includes the cciss driver

Hello,

I think that this will solve the problem :-)

Thank you all!
