[lustre-discuss] nodemap + Slurm: directories have to be world-readable

[Thomas Roth]

Hi all,

we have just switched on nodemap on our 2.12 cluster, with all batch clients being trusted=1 but admin=0, so bascially root-squashing.

The batch system is done by Slurm.

Now all jobs are failing, when the user's directory on Lustre is not world-readable ("permission denied").

RW - Access in the shell is not a problem.



Any site running Slurm and having encountered a similar issue?


Regards,
Thomas


Perhaps I should add that I have used the default nodemap for this, to avoid having to specify many hundreds of non-contiguous batch node IP ranges.
