cannot revert a container snapshot on RBD

[kifeo]

I found that reverting a container snapshot fails and cannot be done.

replication scenario :
- deploy a debian template on proxmox ceph
- snapshot the CT
- touch toto in the vm
- shutdown th CT
- revert (rollback) : rbd snapshot vm-103-disk-0 to 'test' error: Rolling back to snapshot: 0% complete...failed.

Wanted to raise this, maybe I'm doing it wrong ?

Hi,

is the cluster healthy?

Hi, yes the cluster is healthy

Hi,

I can confirm this is a Bug.
The poststop-hookscripts are not applied and so the rbd image stays mapped.
as a temporary workaround, you can unmap the rbd image manually.
