Pause or disable cephadm

If cephadm does not behave as expected, you can pause most of the background activity or disable it completely.

Pause cephadm with the following commands:

Example

[ceph: root@host01 /]# ceph orch pause

This stops any changes, but cephadm periodically checks hosts to refresh it’s inventory of daemons and devices.

If you want to disable cephadm completely, run the following commands:

Example

[ceph: root@host01 /]# ceph orch set backend ''
[ceph: root@host01 /]# ceph mgr module disable cephadm

Note that previously deployed daemon containers continue to exist and start as they did before.

To re-enable cephadm in the cluster, run the following commands:

Example

[ceph: root@host01 /]# ceph mgr module enable cephadm
[ceph: root@host01 /]# ceph orch set backend cephadm
