After upgrading to 12.2 from DVD, at boot the stock 3.4.6 kernel throws
this message, once for each partition:

The arrays are still mountable and accessible after the system comes up.

I am having the exact same problem with my root on LVM since I applied the
latest kernel update yesterday. :(

For me the following solved the problem:

Boot into rescue system (on Install-DVD). Simply enter `root` when asked for a

Chroot into the system you want repaired. In my case:

mkdir /foo
vgchange -a y
mount /dev/noraid/root /foo
mount --bind /proc /foo/proc
mount --bind /dev /foo/dev
chroot /foo

Create a fixed initrd. I did add `lvm` to `INITRD_MODULES` in
`/etc/sysconfig/kernel`. However, as `mkinitrd` claims not to find any such
module I assume the problem simply that the initrd itself was broken, not that
lvm was missing.


Exit your chroot and reboot.


That fixed it for me. Hope you are as lucky.
