The slurm-7.0.0-17.11.05.00.01 roll seems to have been built without native x11 support. If libssh2-devel is installed, the slurm configure script will automatically enable x11 support but without that it disables it. "ldd /usr/sbin/slurmstepd" doesn't show a dependency on libssh2.so.1 which it would if x11 support was enabled and an attempt to enable it in slurm.conf gets the error:
scontrol: error: X11 forwarding not built in, cannot enable.
Thanks

Thanks for rebuilding with X11 support but after playing with it for a while and reading the slurm list archives, I get the impression it's not yet stable enough for production. It sort of works but in an environment where home directories are shared over NFS (typical of rocks installations) xauth times out before the connection completes.
There's a patch to help with this but that doesn't work in all cases. The response on the mailing list is that it won't be fixed before slurm 18, so it might be better to drop it for now. We've gone back to using the spank plugin for X11 which is old but still works reliably.
Thanks again and apologies for any wasted time.

Hi Ian,
Thank you for the report.
I now have published slurm-7.0.0-17.11.05.00.02,x86_64.disk1.iso. Slurm is now build with X11 support.
After updating the roll, you don't need to reinstall the compute nodes. Simply run the command:
yum -y update and restart slurmd.
Best regards
Werner
