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

[Sebastien Buisson]

Hi,

As explained in the Lustre Operations Manual in this section:
https://doc.lustre.org/lustre_manual.xhtml#idm139831573757696
it is required to define a nodemap that matches all server nodes, with admin and trusted to 1.
Have you?

Cheers,
Sebastien.

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.
