I have a 4 drive LVM PV Group. I had one drive fail (Ok, I broke it installing it in a new case.) so I swapped it for another drive and recovered the remaining data.
After a reboot I got stuck at a file system scan for the
/dev/mapper/storage-storage1 LVM. I canceled that and rebooted with the fastboot flag to skip it. I ran
fsck on the
/dev/mapper/... device and it ran for awhile before I ran out of RAM and it failed. Now 2 of the physical drives show no partition table and are missing from the VG. They did have one LVM partition spanning the entire drive on each.
I want to get rid of this LVM and set up a RAID5 configuration anyway but I would have liked to backup some of the data on the LVM first. (Nothing that can not be downloaded again but it would save a lot of time to backup locally first.)
Is there anything I can try to recover the missing partition info on the two drives? The host OS is Debian 7 with OpenMediaVault.
