I've added new volume group with single logical volume:
pvcreate /dev/sdb1
vgcreate -s 32m xxx_vg /dev/sdb1
lvcreate -l 1234 -n yyy_lv xxx_vg
and rebooted the server after it. When booting, the kernel panics with can't
mount root file system. Looking at the console output, it seems all volume
groups and all logical volumes on them were imported correctly.
However, if I go to rescue mode, and re-create initrd image:
chroot /mnt/sysimage
cd /boot
rm initrd-ver.img
mkinitrd initrd-ver.img ver
lilo
then reboot, the server comes up just fine.
This is kind of wierd. The root file system was available (at least according
to vgscan output which claimed it imported my sys_vg volume group with all the
logical volumes I have on it), I haven't touched sys_vg at all, however unless
I actually rebuild initrd image, the kernel fails to mount it!?
