• 00:00 MEH: after reboot ipp023, restarted summitcopy, registration, stdscience for clean start. ran regtool -revertprocessedimfile -dbname gpc1.
• 01:30 MEH: watching processing summit/registration getting stalled often, looks like ipp018 often not responding for replication stage, putting into repair (too many trying to replicate to ipp018 with so many red disks?). been a problem for a while with

  INFO: task mount.nfs:29470 blocked for more than 120 seconds.
  

  • seems to have now moved the problem to ipp017.. but handling better. ipp018 may want a reboot (been a whole ~23d since last one).
• 07:40 oddly, seems like manually running regtool was needed when this has been automatic in the past (and sometimes still is). has something changed in code related to it, is there a number of tries attempted and then stops?

  regtool -updateprocessedimfile -exp_id 536377 -class_id XY11 -set_state pending_burntool -dbname gpc1
  

• 08:45 Bill restarted pstamp and update pantasks in order to have clear success and failure counts.
• 09:15 MEH: ipp023 down again.. same problem as last night. rebooting and taking out of processing Ipp023-crash-20121022
• 10:25 MEH: nightlyscience 99% through (finished downloading ~09:20)
• 12:15 MEH: Bill changed retention for M31+STS for MPG folks, when nightlyscience finished need to make install in src/ipp-20120802/ippconfig/recipes/ (shutting down and restarting all pantasks)
  • this may challenge available disk space on 20TB machines, 8/30 aren't in repair or red.
• 12:45 MEH: Chris added check for registration burntool stalling condition to ippScripts. pantasks stopped (mostly distribution, pstamp only active) and rebuilt ippScripts only.
• 12:50 MEH: reboot testing ipp046 after BIOS battery replacement hasn't been done yet. does it boot on power cycle properly now -- no. sending email to Hayden, Gavin, Rita to ask the MHPCC people to look into it.
• 13:25 MEH: reactivating the LAP label

  labeltool -dbname gpc1 -updatelabel -label LAP.ThreePi.20120706 -set_active
  

• 14:40 MEH: Rita reported loss of AC for the ippbXX nodes, so shutting down until repaired tomorrow.
  • replication pantasks stopped
  • neb-host ippb00 down etc for all 4
• 14:50 MEH: many LAP faults, turning all reverts off to avoid wasting cycles on the same faults until fixed (many of them), or nightly science starts.
• 15:10 MEH: adding deepstack's compute3 into pstamp for 100% increase in nodes to help move through MOPS request.
• 17:00 MEH: something is spiking load >150 on stsci nodes, skycell_jpeg is very backlogged
• 19:00 MEH: some 43 camera distribution fault 2 from 10/16, reverted and cleared disttool -revertrun -dbname gpc1 -fault 2 -label ThreePi.nightlyscience
• 22:30 MEH: checked on the exposures o6218g0006o--o6218g0054o reported to be missing for DQstats from otis, they all appear to be processed and there on the datastore from 10/18.

• 07:00 MEH: only 346 exposures, mostly finished. no registration hangups last night.
• 10:30 MEH: looking at the IPP->OTIS Problem Exposure Notification from 10/17-10/18. Todd notes there was a FITS formatting anomaly with [Header missing END card.] for those, but the following days is okay. Me manually loading dqstats.9999.fits with pyfits 2.0.1dev428 locally seems okay.
• 11:40 MEH: ippbXX machines back online now that AC is fixed at ATRC. ippb00.0/1 and ippb03 were all in repair, keeping ippb03 in repair but putting ippb00.0/1 into up. ippb02 are very full, setting all to repair.
• 11:50 MEH: working on fixing faulted LAP chips

  -- regenerated burn.tbl using ipp-trunk/tools/fixburntool, important to note the replicated version of these end up on the stsci nodes like nightly science is sometimes doing as well.

• 13:45 MEH: preparing for full restart of pantasks and rebuild with Chris' change to ippconfig to start cleaning warps. stdscience needing its regular restart.
