Hello,

A while back I asked about the troubles I was having with Ceph-Ansible when I kept existing OSDs in my inventory file when managing my Nautilus cluster.

At the time it was suggested that once the OSDs have been configured they should be excluded from the inventory file.

However, when processing certain configuration changes Ceph-Ansible updates ceph.conf on all cluster nodes and clients in the inventory file.

Is there an alternative way to keep OSD nodes in the inventory file without listing them as OSD nodes, so they get other updates, but also so Ceph-Ansible doesn't try to do any of the ceph-volume stuff that seems to be failing after the OSDs are configured?

Are you using LVM or LVM-batch? If the former, you might find --skip-tags prepare_osd Does what you want. I use that because otherwise ceph-ansible gets sad if your device names aren't exactly what it's expecting.
