[slurm-users] Managing Local Scratch/TmpDisk

How are folks managing allocation of local TmpDisk for jobs?

We see how you define the location of TmpFs in slurm.conf.

And then how the amount per host is defined via TmpDisk.

Then the request for srun/sbatch via --tmp=X

However, it appears SLURM only checks the defined TmpDisk amount when allocating tmp, not the actual space available on disk.

That is to say, for example, if during the course of its run, a job uses more of the TmpDisk space than it requests initially, SLURM doesn't check the actual disk space available for other jobs.

The only notification that you will get is when your jobs run out of space or the defined TmpFs is full.
