PCS is replacing crmsh from Ubuntu Lunar onwards

[Lucas Kanashiro]

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:

https://discourse.ubuntu.com/t/ubuntu-ha-migrate-from-crmsh-to-pcs/34818

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


Lucas Kanashiro.
