Hi, I've logged a bug report (https://tracker.ceph.com/issues/43296?next_issue_id=43295&prev_issue_id=43297) and Alwin from Proxmox was kind enough to provide a work around: ceph config rm global rbd_default_features; ceph config-key rm config/global/rbd_default_features; ceph config set global rbd_default_features 31; ceph config dump | grep -e WHO -e rbd_default_features; WHO MASK LEVEL OPTION VALUE RO global advanced rbd_default_features 31 Regards David Herselman -----Original Message----- From: Stefan Kooman <stefan@xxxxxx> Sent: Wednesday, 11 December 2019 3:05 PM To: David Herselman <dhe@xxxxxxxx> Cc: ceph-users@xxxxxxxxxxxxxx Subject: Re: Ceph assimilated configuration - unable to remove item Quoting David Herselman (dhe@xxxxxxxx): > Hi, > > We assimilated our Ceph configuration to store attributes within Ceph > itself and subsequently have a minimal configuration file.

I can confirm this bug. It's possible to have the same key present with different values. For our production cluster we decided to stick to ceph.conf for the time being. That's also the workaround for now if you want to override the config store: just put that in your config file and reboot the daemon(s). Gr.
