Hi, Yes both snap create commands were executed as user admin: client.admin caps: [mds] allow * caps: [mgr] allow * caps: [mon] allow * caps: [osd] allow * deep scrubbing+repair of ecpool_hdd is still ongoing, but so far the problem still exists Am Di., 18.

Hi,
In the meantime I did some further test. I've created a new erasure coded datapool 'ecpool_test' and if I create a new rbd image with this data pool I can create snapshots, but I can't create snapshots on both new and existing images with existing data pool 'ecpool_hdd'
just one thought, could this be a caps mismatch? Is it the same user in those two pools who creates snaps (or tries to)? If those are different users could you share the auth caps?

Can you double check if this output is complete? It looks truncated to me -- the debug log part (lines beginning with a timestamp) should be many times longer.
Try collecting it as follows and attach log.txt file:
$ rbd snap create ceph-dev@backup --debug-ms 1 --debug-rbd 20 >log.txt 2>&1
Thanks,
Ilya
