Hello, I'm having a problem draining my cluster's batch queues using setres. Adapting one of the examples given in the clusterresources documentation I attempt to reserve every node and processor in my cluster during our scheduled downtime:
# setres -s 18:00:00_11/18 -e 08:00:00_11/19 -n electricityDowntime ALL I then check the reservations and see that the downtime is there and is applied to all processors along with a few other reservations for pre-existing jobs. To test the reservation I submit a job which requests an excessive amount of wallclock time (Job 918). It's scheduled to start when the downtime finishes which is what I expect: [EMAIL PROTECTED] spool]# showres Reservations ReservationID Type S Start End Duration N/P StartTime 909 Job R -1:21:00 83:06:39:00 83:08:00:00 1/1 Mon Nov 10 15:40:32 912 Job R -1:09:05 4:12:50:55 4:14:00:00 1/1 Mon Nov 10 15:52:27 913 Job R -00:49:57 4:13:10:03 4:14:00:00 1/1 Mon Nov 10 16:11:35 918 Job I 8:14:58:28 91:22:58:28 83:08:00:00 1/1 Wed Nov 19 08:00:00 electricityDowntime.0 User - 8:00:58:28 8:14:58:28 14:00:00 60/480 Tue Nov 18 18:00:00 17 reservations located Unfortunately, upon checking the reservations ~ 10minutes later I find that Job 918 has started despite the reservations overlapping: [EMAIL PROTECTED] spool]# showres Reservations ReservationID Type S Start End Duration N/P StartTime 909 Job R -1:27:25 83:06:32:35 83:08:00:00 1/1 Mon Nov 10 15:40:32 912 Job R -1:15:30 4:12:44:30 4:14:00:00 1/1 Mon Nov 10 15:52:27 913 Job R -00:56:22 4:13:03:38 4:14:00:00 1/1 Mon Nov 10 16:11:35 918 Job R -00:06:15 83:07:53:45 83:08:00:00 1/1 Mon Nov 10 17:01:42 electricityDowntime.0 User - 8:00:52:03 8:14:52:03 14:00:00 60/480 Tue Nov 18 18:00:00 17 reservations located Can anyone help me debug this/explain this behaviour?
