[OOD-users] common NFS for ood data shared with slurm workers

[Anderson, Richard O - (ric)]

We use common NFS mount for /home and several other file systems that the compute nodes can access as users may have files in any/all of those they need to edit.

Subject: [OOD-users] common NFS for ood data shared with slurm workers

Hi all,

when trying to launch a slurm job from within the ood dashboard, i get, in slurmd.log:

[14.batch] error: Could not open stdout file /home/ood/ondemand/data/sys/myjobs/projects/default/4/slurm-14.out: No such file or directory
[14.batch] error: IO setup failed: No such file or directory

similarly, when trying to launch a jupyter notebook, i get:

[39.batch] error: Could not open stdout file /home/ood/ondemand/data/sys/dashboard/batch_connect/dev/jupyter/output/380b6eec-6d71-4a83-8a5e-20398831668a/output.log: No such file or directory
[39.batch] error: IO setup failed: No such file or directory

and that's because that path only exists on the ood node but not on a slurm worker node.
to have this path exist on the ood node and all slurm worker nodes
i'd suggest to use a common NFS they all mount. is that the recommended way to go
or what would you suggest?

thanks in advance.
