Hi All,
I have what I believe to be a pretty basic LVM & RAID setup on my
CentOS 5 machine:
Raid Partitions:
/dev/sda1,sdb1
/dev/sda2,sdb2
/dev/sda3,sdb3
During the install I created a RAID 1 volume md0 out of sda1,sdb1 for
the boot partition and then added sda2,sdb2 to a separate RAID 1
volume as well (md1). I then setup md1 as a LVM physical volume for
volume group 'system'. I left the sda3,sdb3 partitions available for
future use.
Next I created swap, /, /usr, /var, etc. logical volumes in the system
volume group and continued with this install as normal. Everything
went fine. I was able to use the system, reboot, etc., without
problems.
I then discovered that I needed more space in my /var volume than was
available in the system volume group. So, I created another RAID
device, /dev/md2 (using sda3,sdb3), and created an LVM physical volume
on top of that. Finally, I extended the system physical volume to
contain this new physical volume and expanded the size of the /var
volume.
This worked fine, but on reboot I get a ton of errors from LVM saying
that volume with id xxxx-xxxx-xxxx... was not found and the system
automatically reboots. This seems to happen for all volumes, not just
the ones I changed. This error even happens for a separate volume
group (called 'extended') that is on a separate set of disks and was
existing prior to the CentOS 5 install.
Any idea on some step I missed? I know things are still fine on the
disks, as when I boot with the CentOS DVD with the 'linux rescue'
option all RAID & LVM volumes are available for use. So from this it
seems I need to update some CentOS config file?
Here are some config files:

Thanks!
