Google is your friend: http://slurm.schedmd.com/quickstart_admin.html#upgrade It looks like it's not (yet) been changed to include reference to the 16.05.3 version but the general principle is the same. To reinforce what it says there: # always upgrade the SlurmDBD daemon first I would add: # always do a mysqldump of your Slurm database before # upgrading slurmdbd (and after stopping slurmdbd). :-) So you always go in the order of upgrading: * slurmdbd * slurmctld [recompile all plugins, MPI stacks, etc that link against Slurm] * slurmd We use a health check script that defines the version of Slurm that is considered production so we can just bump that number first, wait for all the compute nodes to be marked as drained and then as nodes become idle we can start restarting slurmd knowing that we will never get a job that spans both old and new slurmd's. Best of luck!
