Hello,
I have two identical servers in hardware. I installed both with CentOS.
I did LVM snapshots before updating to test LVM merging.
On one server I merged all filesystem's during boot because they where
mounted when I merged.
The other server I did the snapshots, made my installations and configurations
and made no merge because it worked on the other server.
But I forgot to delete the snapshots and: n the night the server crashed.
It rebooted to recovery kernel because it can't find the lvm volumes (module
dm_snapshots was missing).
Both servers have a difference. When they start one says CentOS (Core) at the
end of the loading bar. The other with the crash says sth. about a dracut-Kernel
while loading.
What do I have to look for?
Partitioning scheme on both servers:
/boot: sda1
/: lvm
/usr: lvm
/var: lvm
Swap: lvm
Thanks in advance
Tim
