I have a very simple system, one controller, one server node. The node
is up.
ubuntu@controller:~$ sinfo
PARTITION AVAIL TIMELIMIT NODES STATE NODELIST
debug* up infinite 1 idle server1
I create a reservation containing the server node but having a start
time many days in advance:
ubuntu@controller:~$ scontrol show reservations -o
ReservationName=foo3 StartTime=2017-07-03T00:00:00
EndTime=2017-07-03T01:00:00 Duration=01:00:00 Nodes=server1 NodeCnt=1
CoreCnt=1 Features=(null) PartitionName=debug Flags= TRES=cpu=1
Users=ubuntu Accounts=(null) Licenses=(null) State=INACTIVE
BurstBuffer=(null) Watts=n/a
ubuntu@controller:~$
I then try to run a (very simple) job, but the job is queued:
ubuntu@controller:~$ srun hostname
srun: Required node not available (down, drained or reserved)
srun: job 630 queued and waiting for resources
squeue suggests the job is queued because the server node is not available:
ubuntu@controller:~$ squeue
JOBID PARTITION NAME USER ST TIME NODES
NODELIST(REASON)
629 debug hostname ubuntu PD 0:00 1
(ReqNodeNotAvail, May be reserved for other job)
Is this the expected behavior and, if so, why?
Thanks
