or to have
behavior more similar to the CentOS 7 CephFS clients?
Do different OS or Linux kernels have greatly different ways they respond
or limit on the IOPS? Are there any options to adjust how they limit on
IOPS?
Thanks,

systemctl, outside of cephadm:*
ssh {osd-host}sudo systemctl stop ceph-osd@{osd-num}

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.

How can I restore the ability to connect with the command-line `ceph`
client to check the status and all other interactions?

good guide that describes not just the Samba smb.conf,
but also what should be in /etc/ceph/ceph.conf, and how to provide the
key for the ceph:user_id ? I am really struggling to find good
first-hand documentation for this.
Thanks,

Is there a workaround for this problem where the container process is

using `cephadm` tools? At last check, a
server running 16 OSDs and 1 MON is using 39G of disk space for its
running containers. Can restarting containers help to start with a
fresh slate or reduce the disk use?
