[slurm-users] Slurm 23.11 - Unknown system variable 'wsrep_on'

Hi all,

I am working on upgrading a Slurm cluster from 20 -> 23. I was successfully able to upgrade to 22, however now that I am trying to go from 22 to 23, starting slurmdbd results in the following error being logged:

error: mysql_query failed: 1193 Unknown system variable 'wsrep_on'

When trying to start slurmctld, I get:

[2024-04-02T15:09:52.439] Couldn't find tres gres/gpumem in the database, creating. [2024-04-02T15:09:52.439] Couldn't find tres gres/gpuutil in the database, creating. [2024-04-02T15:09:52.440] fatal: Problem adding tres to the database, can't continue until database is able to make new tres

Any ideas what could be causing these errors? Is MariaDB 5.5 still officially supported?
