Past backups broken due to CEPH crash

[JanZorz]

Hi,

We had some issues with CEPH due to errors on the eth port, but we solved them quite quickly. Sadly, one VM with quite large disks was broken so it doesn't boot. When booting it it says that it can't find LVM id to boot from, buty also all other tricks with grub rescue failed - apparently the main disk is completely broken.

We have many backups of this VM, going back to October last year, all residing on Proxmox Backup server. I tried to restore older backup image to the proxmox cluster, but to no avail. Restored disk is still broken and it doesn't boot. I tried to restore backup from October into new VM ID, but that one is also broken in a same way.

Apparently after the CEPH failure proxmox system did a scheduled backup of this broken VM to backup server and completely broke all previous backups.

Any idea how to get out of this mess?

Cheers, Jan Zorz

Hello, I have no idea why you are facing this problem but since i assume you restore to ceph storage, and all backups give you the same problem, perhaps try to restore to another storage like a local disk. It's possible that the problem is with ceph/LVM and not the backups. Also, some info about the VM could be of interest here.
