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
