Hi Gerry,
> [2014-08-21T09:30:09.673] fatal: system has no usable batch compute nodes > We see this on our systems (running Slurm + Alps/basil rather than native) when the slurmctld starts before the sdb has a list of batch nodes. It's bitten us when we've set the nodes to interactive rather than batch, and more regularly when we've restarted the sdb and slurmctld has started too early in the boot process. (a quick 'service slurm restart' sorts that tho) Andrew
