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 ~]#

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.
