I've had an issue with a corrupted checksum on a single drive in my raid-6 md after every reboot. Following some instructions online, I stopped the array and recreated it with the --assume-clean option. The md created fine (although after reboot the drive still demonstrates a corrupted checksum, so I think the drive is borked), but the partition table on it is gone. I'm really hoping my data isn't gone.
When I run testdisk, it does immediately find an LVM2 partition in Quick and Deep scans, and while it and the md are both 20TB/18TiB, it says the hard-drive is too small:
Code: Select all
Disk /dev/md0 - 20 TB / 18 TiB - CHS 4883782460 2 4
The harddisk (20 TB / 18 TiB) seems too small! (< 23 TB / 21 TiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partitions can't be recovered:
Partition Start End Size in sectors
Linux LVM 512 0 1 588815615 1 4 39070259200
The fact that it can see
the partition gives me hope that my data isn't gone, but I'm not sure what to do at this point.

There is no partition table on LVM2.
