Logical volumes gone. What's next?
On a Debian 64AMD server, I created two raids. /dev/md0 and /dev/md1.
On top of /dev/md1 I created a partition table and a volumegroup with 2 lv's to be used with lvm for a VTL.
After a reboot to enable the modules for the VTL software, the Lv's with the volumegroup and the partition table are gone.
What's going on here? Does anyone knows what could happen?
I tried to re-assemble, without result.
mdadm --examine /dev/md1:
mdadm: No md superblock detected on /dev/md1.
