dcalph001 slurmd log

Hi,

I have recently upgraded 15.08.5 => 15.08.6 as per:
http://slurm.schedmd.com/quickstart_admin.html#upgrade

After the upgrade observed clear anomaly

======================================================================================

Please note: "CPUAlloc=36 ... CPULoad=56.00" I have checked the situation on host=dcalph001  and indeed JobID=1131 is running despite that slurmctld thinks that it is suspended. Moreover that is clear from slurmd log od dcalph001 that JobID=1131  was deliberately resumed by slurmd around slurmctld restart.

Please be not confused by 2 hours difference. That happened because we also changed CST=>PST timezone on our servers. Since slurmctld had been restarted first it was already reporting PST while slurmd was still technically in CST at that time.


Not sure if that 15.08.6 or 15.08.5 issue though. Because when that wrong resume happened slurmcld was at 15.08.6 and affected slurmd was still at 15.08.5.

Hi,
    thanks for your report. We will examine the data you have provided and
get back to you.

David

Comment 4 David Bigagli 2015-12-22 23:01:36 MST

Hi,
   I cannot reproduce what you reported and Slurm is not suppose to resume
or change state of job after reconfigure or restart. 
The logs show that 'scontrol resume 1131' command was ran to resume the job
on purpose that's a clearly logged sequence which can be reproduced easily.

David

Comment 5 Sergey Meirovich 2015-12-23 02:08:06 MST

Hi David,

Where do you see manual resume? There should be "Processing RPC: REQUEST_SUSPEND(resume) from uid=..." in slurmctld log that is coming from next:
/src/slurmctld/proc_req.c:	info("Processing RPC: REQUEST_SUSPEND(%s) from uid=%u",

However that is not present in the slurmctld log that is attached.

====================================================================
root@debian:/mnt/dnld# zcat slurmctld.gz | grep REQUEST_SUSPEND
root@debian:/mnt/dnld# 
====================================================================

SchedMD clearly stated to us that manual suspend/resume is dangerous:
http://bugs.schedmd.com/show_bug.cgi?id=2031

So we are strictly refraining from it on our production cluster.

Comment 6 David Bigagli 2015-12-27 23:09:42 MST

Hi Sergey,
         yes my initial thought was not correct. When gang scheduling is configured at reconfiguration/restart of the slurmctld the jobs are resumed
by the gang scheduling plugin but they are also suspended immediately.
What seems to happen in your case is that the job got resumed one more time.
Do you observe this for all jobs or just sporadically?

David

Comment 8 Sergey Meirovich 2015-12-28 00:19:26 MST

Hi David,

I have seen that only once so far.

Indeed I see the behavior you have explained for other JobID - there was two jobs in suspended status during last restart: 
=========================================================================================
root@debian:/mnt/dnld# zgrep 'Recovered ' slurmctld.gz | grep State=0x2 | grep 2015-12-21
[2015-12-21T07:42:31.049] Recovered JobID=1131 State=0x2 NodeCnt=0 Assoc=166
[2015-12-21T07:42:31.049] Recovered JobID=2019 State=0x2 NodeCnt=0 Assoc=166
root@debian:/mnt/dnld# 
=========================================================================================

JobID=2019 had resumed and immediately suspended exactly as you have explained:

Not sure why that didn't happen the same for the JobID=1131

Thanks for the update. I was able to reproduce the problem once when I used
your configuration and enabled the gang scheduling. We are now investigating
a possible cause of the problem.

Comment 14 Moe Jette 2015-12-28 04:52:33 MST

Created attachment 2548 [details]
fix for bug

I was able to confirm the behaviour described. The original logic was resuming all jobs when slurmctld restarted or was reconfigured, then suspended jobs. This change leaves suspended jobs suspended.

Comment 15 Moe Jette 2015-12-28 04:54:00 MST

The fix will be in version 15.08.7 when released, likely in mid-January. The commit is here:
