Hi, We are using Percona XtraDB cluster to achieve HA for our Slurm databases. There is a single virtual IP that will be kept on one of the cluster's servers using keepalived.

Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] Community: What do you do to ensure database reliability in your SLURM environment? We can have multiple controllers and multiple slurmdbds, but my understanding is that slurmdbd can be configured with a single MySQL server, so what do you do? Do you have that “single MySQL server” be a cluster, such as Percona XtraDB? Do you use MySQL replication, then manually switch to slurmdbd to a replication slave if the master goes down? Do you do something else? Thanks. Daniel
