Hello all. I'm seeing something strange related to group memberships and how it bothers Slurm. Appreciate any ideas to understand what is going on. It appears that only the primary group of the user is propagated when Slurm runs a job. The additional group memberships vanish. This is not expected behaviour. I'm wondering if I'm missing any configuration with slurm. navtp@console2:~> id uid=29865(navtp) gid=510(finland) groups=510(finland),508(nav),5001(ghpc) context=unconfined_u:unconfined_r:unconfined_t:s0- s0:c0.c1023 navtp@console2:~> ssh c07b07 id uid=29865(navtp) gid=510(finland) groups=510(finland),508(nav),5001(ghpc) context=unconfined_u:unconfined_r:unconfined_t:s0- s0:c0.c1023 navtp@console2:~> srun -p nav hostname slurmstepd: error: couldn't chdir to `/usr/home/nav/finland/navtp': Permission denied: going to /tmp insteadc07b07.ghpc.au.dk

As you can see, the user - navtp is part of finland, nav, and ghpc groups. finland being primary group. when I ssh into a node directly, the groups are configured correctly as shown by ssh command. But, through Slurm the additional groups vanish. This means that the user now cannot access some directories they normally would. I believe this is also the reason for the slurmstepd errors. How can I make Slurm retain all group memberships? Thanks, Aravindh -- Aravindh Sampathkumar aravi...@fastmail.com
