Ugh. Baer needs caffeine, badly. What I meant to say was:
I'm fairly sure that the user didn't explicitly request this reservation, which makes me suspect that the MAGNETIC (formerly PROMISCUOUS) flag on the reservation is causing the reservation to attract jobs even if they aren't allowed to access the reservation's resources.
BTW, I should also mention that if I manually remove the reservation setting from these jobs (e.g. "scontrol update jobid=13817 reservation="), they start running immediately. Hi I can recreate this. I let you know when the fix will be in repo. Dominik Any updates on this? Any updates? We have some use cases around classroom HPC usage where working magnetic reservations would be useful. Troy, a fix for this and other issues with magnetic reservations found while looking at this has been checked into 20.02.6 commits 815751a629b3e3..4948d1adc87efc. If you have any other issues after testing please reopen this or open a new bug on the matter. Thanks for reporting and helping figure it out :). |
