Hi Wes,
thanks the `ceph tell mon.* sessions` got me the answer very quickly :-)

Why would I want to learn Kubernetes before I can deploy a new Ceph
cluster when I have no need for K8s at all?

What is the advantage of podman vs docker ? (I mean not in general but for

Docker comes with the Docker daemon that when it gets an update has to
be restarted and restarts all containers. For a storage system not the
best procedure.

You can ask the monitor to dump its sessions (which should expose the IPs
and the release / features) you can then track down by IP those with the
undesirable features/release
ceph daemon mon.`hostname -s` sessions
Assuming your mon is named after the short hostname, you may need to do
this for

This will have no positive effect. The monitors will not alter the
number of ranks (i.e. stop a rank) if the cluster is degraded.

Hi,
Our cluster is currently running quincy, and I want to set the minimal
client version to luminous, to enable upmap balancer, but when I tried to,
I got this:

require_min_compat_client to luminous: 2 connected client(s)

cephadm.
The ceph-ansible project writes in its README:
NOTE: cephadm is the new official installer, you should consider
migrating to cephadm.

Hello Ceph users,
We've been having an issue with RGW for a couple days and we would
appreciate some help, ideas, or guidance to figure out the issue.
We run a multi-site setup which has been working pretty fine so far. We
don't actually have data replication enabled yet, only metadata
Hi David
Reducing max_mds didn't work. So I executed a fs reset:
ceph fs set atlassian-prod allow_standby_replay false
ceph fs set atlassian-prod cluster_down true
ceph mds fail atlassian-prod.pwsoel13142.egsdfl
ceph mds fail atlassian-prod.pwsoel13143.qlvypn
ceph fs reset atlassian-prod
ceph fs
