Hi, When rbd client try's to set RBD per pool QoS settings, the settings set's successfully, but also rbd prints this message [root@api1]# rbd --id rbd_user config pool set rbd.example-1 rbd_qos_read_bps_limit 20001 2026-06-19T13:18:30.623+0000 7ff12d46a3c0 -1 librbd::PoolMetadata: update_pool_timestamp: failed to notify clients of pool config update: (13) Permission denied Seems this is part of code [1] The caps is: client.rbd_user key: <snip></snap> caps: [mgr] allow command "service status" caps: [mon] profile rbd, allow command "osd blacklist", allow command "osd blocklist" caps: [osd] profile rbd The question is: * should non-admin account allowed to write update_pool_timestamp [by design]? * should 'profile rbd' be allowed to write update_pool_timestamp [dev's just forget add this to profile]? * can be possible 'allow command' for this via current caps? Thanks, k [1] https://github.com/ceph/ceph/blob/main/src/librbd/api/PoolMetadata.cc#L23-L4...
