Hello Roland,
thanks for your reply.
what is the slurm package version mentioned in /usr/share/doc/qlustar-image/slurm.packages.version (on the booted node)? Should be 17.11.9.2-ql.3+10-xenial.
Yes, it is.
So I assume 17.11.9.2 should be the correct version. Maybe some mismatch with the chroot?
As far as I can tell from the source, slurm versions are three bytes only, so the patchlevel (".2") is left out.
I tried to run my code on the master, and it worked without the error. I also checked md5sums between node and master for auth_munge.so (and all other plugins in the same location), and for slurmd and slurmstepd, and they all match up. So something fishy is going on, but I don't know what yet.
I'll keep you posted.
