storage didn't come after reboot

batu · Oct 16, 2018

Hello,

I have been using proxmox since July, and I have 7 virtual servers running on it. I had an electrical problem with the storage. Reboot proxmox and storage doesn't reach. I searched almost the entire forum. Do you have any idea how to mount it back ?

Data is on pve disk. When i try to fsck says magic superblock errors.

Code:

afaics, your 2tb disk (/dev/sdb) has no partitions on it, and is not referenced by anything
you have 1 vg that is only on /dev/sda
that contains 1 thinpool 'data'
and you have 2 storages pointing to the 'data' thinpool on /dev/sda (so they are really the same storage)

also something is wrong with your output, since pvesm lists a 'Data' storage that does not exist in your config, that should not happen
