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?

I get that error in my log every startup, and it's benign. That variable only exists on a Galera Cluster, so seeing it on a simple mariadb instance is to be expected and benign.

Check permissions of your database user, it has to be able to create and alter tables.
Thanks! I realized I made a mistake and had it still talking to an older slurmdbd system.
