Hi,
We assimilated our Ceph configuration to store attributes within Ceph itself
and subsequently have a minimal configuration file. Whilst this works perfectly
we are unable to remove configuration entries populated by the assimilate-conf
command.
Ceph Nautilus 14.2.4.1 upgrade notes:
cd /etc/pve;
ceph config assimilate-conf -i ceph.conf -o ceph.conf.new;
mv ceph.conf.new ceph.conf;
pico /etc/ceph/ceph.conf
# add back: cluster_network
# public_network
ceph config rm global cluster_network;
ceph config rm global public_network;
ceph config set global mon_osd_down_out_subtree_limit host;
Resulting minimal Ceph configuration file:
[admin@kvm1c ~]# cat /etc/ceph/ceph.conf
[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
Ceph configuration entries:
[admin@kvm1c ~]# ceph config dump

Note the duplicate 'rdb_default_features' entry. We've switched to kernel 5.3
which supports object-map and fast-diff and subsequently wanted to change the
default features for new RBD images to reflect this.
Commands we entered to get here:
[admin@kvm1b ~]# ceph config dump | grep -e WHO -e rbd_default_features

[admin@kvm1b ~]# ceph config rm global rbd_default_features
