Description
We assimilated our Ceph configuration file and subsequently have a minimal config file. We are subsequently not able to remove configuration entries.
Present on 7 Ceph 14.2.4 clusters and confirmed by Stefan Kooman to also have affected him when he upgraded to Mimic.
Commands:
cd /etc/pve; ceph config assimilate-conf -i ceph.conf -o ceph.conf.new; mv ceph.conf.new ceph.conf;
Minimal config file:
[global]
cluster_network = 10.248.1.0/24
filestore_xattr_use_omap = true
fsid = 31f6ea46-12cb-47e8-a6f3-60fb6bbd1782
mon_host = 10.248.1.60 10.248.1.61 10.248.1.62
public_network = 10.248.1.0/24
[client]
keyring = /etc/pve/priv/$cluster.$name.keyring
Configuration dump:

Note the duplicate 'rdb_default_features' entry.
We're not able to remove the original 'rbd_default_features' entry that the assimilate-conf command created:
[admin@kvm1b ~]# ceph config dump | grep -e WHO -e rbd_default_features WHO MASK LEVEL OPTION VALUE RO global advanced rbd_default_features 7 [admin@kvm1b ~]# ceph config rm global rbd_default_features [admin@kvm1b ~]# ceph config rm global rbd_default_features [admin@kvm1b ~]# ceph config rm global rbd_default_features [admin@kvm1b ~]# ceph config dump | grep -e WHO -e rbd_default_features WHO MASK LEVEL OPTION VALUE RO global advanced rbd_default_features 7 [admin@kvm1b ~]# ceph config set global rbd_default_features 31 [admin@kvm1b ~]# ceph config dump | grep -e WHO -e rbd_default_features WHO MASK LEVEL OPTION VALUE RO global advanced rbd_default_features 7 global advanced rbd_default_features 31 [admin@kvm1b ~]# ceph config rm global rbd_default_features [admin@kvm1b ~]# ceph config rm global rbd_default_features [admin@kvm1b ~]# ceph config rm global rbd_default_features [admin@kvm1b ~]# ceph config dump | grep -e WHO -e rbd_default_features WHO MASK LEVEL OPTION VALUE RO global advanced rbd_default_features 7
