Hi,
We have had a situation three times where rbd images seem to be corrupt after restoring a
snapshot, and I'm looking for advice on how to investigate this.
We're running Proxmox 7 with Ceph Octopus (Proxmox build, 15.2.17-pve1). Every time
the problem has happened, it has happened after these actions were done with the VM:
(Yesterday)
- VM stopped
- Snapshot created
- VM started
- VM stopped
- Snapshot restored
- VM started (OK)
- Nightly backup with vzdump to Proxmox Backup Server
(Today)
- VM stopped
- Snapshot restored
- VM does not start
On previous occasions we tried to find a solution and when we couldn't, we restored
the VM from backup, which solved the problem. Now this happened to a test system, so
we've left the situation as is and maybe get to the root cause.
Some observations:
* We're using krbd
* The PBS backups don't allow file restore if the backup was made from a
"broken" image
* After mapping the current image, it doesn't seem to contain a partition table
There's a thread on the Proxmox forum about this issues as well[1].
If anyone could give some advice about how to proceed from here, I'd be very
grateful.
Best regards,
Roel
PS: An upgrade to Pacific has already been planned.
