[SOLVED] CEPH Error with 5.4.5

[GPLExpert]

Hello,

I Have two cephs cluster and i moved one vm disk from one to another with set delete the source disk.

So now i have one unused disk 0 on the old ceph pool.

I unset the protected vm and i try to delete the disk.

I Get :
Error with cfs lock 'storage-myceph': rbd snap purge 'vm-600-disk-2' error. Removing all snaphots: 0% complete.... failed

There are no snapshots.

Any ideas ?

It seems you have two CEPH Storages with identical Disk names. Are you sure, there is no Snapshot existing anymore?

The unused disk appear after moving.

The unused disk appear after moving.

What was the output of the move disk? I may be, that it couldn't delete the image and might have written the reason for it.

Error with cfs lock 'storage-myceph': rbd snap purge 'vm-600-disk-2' error. Removing all snaphots: 0% complete.... failed

As @sb-jw said, are you sure all snapshots are gone? With that, I mean, the snapshots made with Ceph tools directly, as the info for those are not written to the vmid.conf.

rbd -p <pool> ls -l

ok i finnaly found and resolve my problem.

I used rbd snapshot. so before moving on another ceph cluster, we have to delete snapshot before.
This snapshot are not seen on proxmox.

Warning : not forget to unprotect snapshot if not : error

After i can move without problem

Thanks Alwin for the info.
