I have an LVM partition on one of my disks:
Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0007b303 Device Boot Start End Blocks Id System /dev/sdb1 63 976773167 488386552+ 8e Linux LVM
After a clean reboot of my system, the volume group did not show up. I tried running vgscan, but that did not find any volume groups:
root@luxembourg:~# vgscan --ignorelockingfailure --mknodes Reading all physical volumes. This may take a while... No volume groups found No volume groups found
Also, pvs does not find a physical volume on my LVM partition:
root@luxembourg:~# pvs /dev/sdb1 No physical volume label read from /dev/sdb1 Failed to read physical volume "/dev/sdb1"
What happened with my LVM volumes? Could that be related to the reboot? How can I recover them?
