Hello, I find myself with a list of subvolumes in the|no_group|subvolume group, which, if I understand correctly, is a special subvolume group. Actually, Manila created all these subvolumes without specifying a subvolume group. Following an unexpected power outage and a restart, it no longer works. Manila can no longer create subvolumes, and I can no longer manipulate my subvolumes. For example: content_copyCopy code |cephfssubvolumermcephfsbidulestef ErrorEINVAL:invalidvaluespecifiedforceph.dir.subvolume| However, the state of my cluster is not critical. I only have: * 248 PGs not deep-scrubbed in time * 517 PGs not scrubbed in time My Ceph version is: content_copyCopy code |cephversion19.3.0-4637-g42c1c3d4(42c1c3d42aaa0b6c9bcbccb51c8b397fb980aa9f) squid (dev)| My CephFS mounts remain functional. If anyone has information about this, I’d appreciate it. Alternatively, how can I continue creating subvolumes without specifying a subvolume group? Thanks, Stéphane -- Delmotte Stéphane Laboratoire de Biométrie et Biologie Évolutive.
