Rocky have not offered the pacemaker + clvmd +gfs2 cluster. wonder how long could be to add on?
I’m pretty sure pacemaker is in the Rocky “HighAvailability” repository. GFS2 should be included in the default kernel drivers, and there’s a “gfs2-utils” package you can install to interact with it.
Looks like clvm has been deprecated in favor of
lvmlockd in the lvm2-lockd package.
I haven’t actually set any of these up before, sorry. Good luck with your migration!
