Hi,
The Canonical Server team has been maintaining/recommending crmsh as the main tool to manage Corosync/Pacemaker clusters, but starting in Ubuntu 23.04 Lunar Lobster we will replace crmsh with PCS. PCS was promoted to the main Ubuntu repository and is now fully supported by Canonical. For Ubuntu 23.04 Lunar Lobster, both, PCS and crmsh, will be in main and supported, but from Ubuntu 23.10 onwards PCS will be the only supported and recommended tool to manage Corosync/Pacemaker clusters by the Server team.
This is a warning for the crmsh users so they can plan for the migration to PCS, since the next Ubuntu LTS release (24.04) will have PCS as the recommended and supported tool for the purpose of managing Corosync/Pacemaker clusters.
The Canonical Server team tried to create a page in the Ubuntu Server guide to help users migrate from crmsh to PCS:

If you have any questions do not hesitate to contact us (Server team).
Lucas Kanashiro.
