Proxmox VE 5 and Ceph Cluster - application not enabled on 1 pool(s)

[nslave]

Hi,
I have a 3 node Proxmox VE 5 cluster. There is a ceph cluster running on the same hardware with 1 osd per physical machine. Everything works fine except that I get an warning from ceph "HEALTH_WARN application not enabled on 1 pool(s)"

I have 1 pool with size/min = 3/2, pg_num = 128 and 3 osds

While googling about the topic I came across cephs documentation and it stated that pools need to be associated with application before use. I have virtual machines stored in the ceph cluster and they are running, so I am not sure if it is safe to follow cephs documentation and run:

ceph osd pool application enable {pool-name} {application-name}

Any suggestions?

I think that is safe. But you run only 3 OSDs - this is IMHO not enough (>12 is better).

You should run

ceph osd pool application enable {pool-name} rbd

Thanks, I've run it and everything is ok. cluster [INF] Cluster is now healthy

Had same error here ... after power interuption of 1 node (test) all VM's did go to the correct priority group but indeed had the same error message ... a bug ??
