Hello everyone.

Does anyone know of any problems that might occur when running LVM under
Redhat 7.2?

This is my lvm setup, on two 120gb disks and two 100gb disks.

I am able to both install, and setup lvm without any trouble at all, but it
seems the system gets really unstable. I have tried using both the Redhat
2.4.7-10 kernel (the one redhat 7.2 ships with, and the 2.4.17 kernel. I
have also tried using both lvm 1.0.2 and 1.0.3.

When reinstalling, i first export the lvm setup, do the system reinstall,
install lvm, compile new kernel, then when it is up and running, i import
the lvm setup from the other disks. All this seems to be running fine.

But when running normally, the system seems to get itself into a lot of
'Kernel Oops' problems. I have never seen these before, but now i get them
all the time. They either cause pretty much every application i try to run
after the Oops to segfault, or they simply freeze the system. When it gets
back up, and the system needs to be fsck'ed i also experience a lot of
problems getting fsck to run properly. when running fsck /dev/hda1 (which is
a normal ext2 partition, not lvm) i will get the same Kernel oops, and fsck
will fail. I will eventually get the system back up and running normally,
but it takes time. Other commands that i have seen give the same kernel oops
are umount, fsck, proftpd and smbd... I found two examples of this Kernel
Oops code in /var/log/messages, and have included them below, if anyone is
able to gather any information from them.


Any input as to why the system is so unstable would be highly appreciated.
Does the system dislike that i set the PE size to 32? Are there any problems
caused by running lvm under Redhat 7.2? (If so, I could go back to 7.1)


Kind Regards
