I was working through updates of CentOS and packages on each of the Ceph
storage nodes of a cluster, and I hit an issue after I updated a package
`ceph-osd` on the original Ceph node of the cluster.
1. Before the updates, the Ceph cluster was running 15.2.3 version
2. After the update of the package with `dnf install ceph-osd`, I was
unable to check the status any more with `ceph -s`:
2021-06-14T14:01:53.216-0500 7efdef7fe700 -1 monclient(hunting):
handle_auth_bad_method server allowed_methods [2] but i only support [2]
[errno 13] RADOS permission denied (error connecting to the cluster)
3. The `ceph -v` command now shows as version 15.2.13.
Based on other reported issues this could be due recent changes with
security fixes ( https://docs.ceph.com/en/latest/security/CVE-2021-20288/ )
that were introduced in 15.2.11.
This cluster had originally been built with `cephadm` tool and
containerized daemons.
How can I restore the ability to connect with the command-line `ceph`
client to check the status and all other interactions?
Thanks,
Matt

It appears what happened:
1. This host was a MON host, and was the only listed MON in the
/etc/ceph/ceph.conf file.
2. The MON went out of quorum with the other 4 monitors.
3. After adding all MON to the /etc/ceph/ceph.conf, then the `ceph -s`
command worked again.
4. After restarting the host, the MON was able to get back in the quorum
with the other monitors
I think the issue was that when the MON was out of quorum, the ceph client
could no longer connect when only having that MON as an option.
Problem is solved -
