Ceph 20.2 Tentacle Release Available as test preview and Ceph 18.2 Reef soon to be fully EOL

[jsterr]

We also did 15 upgrades from ceph 19 to 20 in nested pve-environments (all clean installs from training) all went fine without issues. The only thing which was not 100% clear howto check what mds-services are standby via cli:

Take all standby MDS daemons offline on the appropriate hosts with:

systemctl stop ceph-mds.target

We looked at the webui to find out. Adding a cli command might be also useful / as people are already on cli. Rest went smooth, my error from above did not happen in all those clean installs.
