I have a test cluster set up with Licenses=node*24 I have a simple reservation defined using : scontrol create reservation=test user=analysis licenses=node*3 starttime=now duration=infinite which is verified using scontrol show reserv ReservationName=test StartTime=2011-09-20T10:21:12 EndTime=2012-09-19T10:21:12 Duration=365-00:00:00 Nodes= NodeCnt=0 Features=(null) PartitionName=rsl Flags= Users=analysis Accounts=(null) Licenses=node*3 However using: srun --reservation=test --licenses=node myjob gives: srun: Requested reservation not usable now srun: job 502 queued and waiting for resources This is using Slurm 2.2.1, do I just need to upgrade to a newer version?
