[slurm-dev] Re: RebootProgram - who uses it?

[Lachlan Musicman]

John, thanks. Yes, I have implemented reboot guard, which was why I was
asking if the config just wanted the link to a bin or could take a command
to execute.

Aaron, kind of. I noticed the anomaly yesterday for the first time and my
manager pointed me to this

Like Busybox, systemctl has reboot compiled in..

cheers

[slurm-dev] 17.02.6 and slurm-spank-x11

[Tim Fora]

Hi all,

I just upgraded to latest slurm (then recompiled slurm-spank-x11) and
getting the error below. Does anyone have the plugin working with 17.02.6?

l01 $ srun --x11 /bin/true
srun: job 126410 queued and waiting for resources
srun: job 126410 has been allocated resources
srun: error: x11: unable to connect node compute227
error: unable to open file /tmp/slurm-spank-x11.20126410.0
slurmstepd: error: x11: unable to read DISPLAY value

Good grief. "reboot" is a legacy tool?!?! I've about had enough of systemd.

Lachlan, in the Name of the Wee Man, so 'reboot' is now a 'legacy tool'
https://access.redhat.com/solutions/1580343

Jeez... Look HPC compute node - I'm in charge, gottit? Yeah, fight back all
you like with systemd, but I can pull the power plug.
Let's see you deal with that one.
