[slurm-users] AllowGroups for Partition not working?

[Matthias Leopold]

Hi,

I'm trying to use AllowGroups for partition configuration in my Slurm
21.08 cluster. Unexpectedly this doesn't seem to work. My user can't
submit jobs although he is member of group mentioned in AllowGroups:

srun: error: Unable to allocate resources: User's group not permitted to
use this partition

Slurmctld has been reconfigured with "scontrol reconfigure", user has
freshly authenticated, "id" for user shows allowed group. My nodes use
Samba winbind for NSS info.

What's wrong?

thx
Matthias

Hi Matthias, 

Before you start digging deeper into this, I would recommend restarting the `slurmctld` service. I've had similar issues where `scontrol reconfigure` wasn't enough for certain configuration changes.

Marko

Thanks, but unfortunately that didn't help.

You should check whether the relevant group's members can be seen using
command `getent group <group name>`. If not, you probably need to
add/change the "winbind expand groups" option in smb.conf.

Thanks a lot. That did the trick.
