[slurm-users] Database cluster

[Henkel, Andreas]

Hi Daniel,

We run a simple Galera-MySQL Cluster and have a HAproxy running on all clients to steer the requests (round-Robin) to one of the DB-nodes that answer the health check properly.

Best,
Andreas

 Xand,

Thanks - that’s great to hear.  I was thinking of using Anycast to achieve the same thing, but good to know that keepalived is a viable solution as well.

Best,
Daniel

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.

Regards,
Xand

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
