PS1 IPP Czar Logs for the week 2014.12.01 - 2014.12.07

(Up to PS1 IPP Czar Logs)

Monday : 2014.12.01

• 09:53 Bill: restarted distribution pantasks which was sluggish with diff stage enabled. SAS distribution is all finished except for diff stage.
• 13:00 Bill: ~ippsky is rerunning staticsky and skycal for sas.37
• 17:00 MEH: setting up ippx049+ for ippsky staticsky/cal to use -- manually adding when ready, ~3x should be fine for 50G ram
  • ippx049--x088 have been setup and added temporarily to a x2 group (need split by pdu?), after Haydn's email x089-x092 also -- see x2 group for ones still down
• 22:00 MEH: nightly processing not doing well w/ ippmd and ippsky running (or something else?) -- ipp083-087 overloaded/not responding and stalling registration

Tuesday : 2014.12.02

• 07:11 Bill: started up fullforce in ~ippsky/staticsky (staticsky and skycal are finished except for one skycell that faulted with a data error. It is running now
• 07:30 MEH: registration backed up quite a bit, too many nodes in use -- ippmd stop until nightly finishes
  • looks like something may have started ~0200, nightly rate dropped greatly then as well.. and not just for stdsci -- looking at the storage node network, appears the red storage nodes hit a data block about that time and there it is...
• 08:30 MEH: taking some xNNN nodes out of ippsky until nightly finishes.. then probably could do 4x on those for FF
• 08:40 MEH: an exposure (o6993g0619o) is stalled in registration.. been a while so restart summitcopy and registration (then stdsci once nightly is finished) -- had to manually run

  regtool -dbname gpc1 -revertprocessedexp -exp_id 829654
  

• 09:30 MEH: ipp056,058,060 have space and could be moved out of repair to help ease load on new storage nodes and get nightly finished
  • same for ipp012,013,029,030
  • now get to see those load >50 -- so even when get 10G for ipp083-088 setup, the other 1G systems will get large loads?
• 12:00 MEH: warp growth curve fault --

  warptool -dbname gpc1 -updateskyfile -fault 0 -set_quality 42 -warp_id 1241149  -skycell_id skycell.1616.069
  

• 12:30 MEH: nightly finally finished, while waiting for storage node reboots, going to do the regular restart of stdsci and set to stop
• 12:50 MEH: adding host groups s4,s5 for the new storage hosts ipp067-070,ipp071-088 respectively. will start testing running jobs on them including deep stacks and should not be allocated for any other jobs at this time
• 13:15 CZW: ran check_system.sh stop to ensure IPP processing is off while we do 10G reboots (and hopefully scidb switch).
• 14:00 MEH: not doing the scidb/ippdb01/05 switch, might as well use this standby time to restart the mysql on ippdb01 (been ~10d or so)
  • restarted czarpoll and roboczar on ippc11
• 15:47 Bill: found another bug in skycal. skycal will need to be rerun for SAS.37 (as does fullforce)
• 16:00 MEH: Haydn & Gavin finished config and reboot of storage nodes. CZW tested r/w on storage nodes, look like ready to go. set pantasks to run and shortly after ipp077 crash -- set to neb-host down
• 17:50 MEH: Gavin restored ipp077 back w/ 1G network, problem w/ 10G card? put back to neb-host repair
• 18:30 MEH: ipp013 appears unresponsive.. ipp012 and some others did for brief period of time as well.. neb-host down for a bit just in case..
  • console showing mem check.. looks like it power cycled..
  • ipp008,012,013,014,016,018,037 actually were all power cycled according to ganglia.. oh why..
• 19:00 MEH: nightly seems to be stalled.. lanl stdlocal and ippmd stop..
  • restarted registration seems to have cleared the problem... was stuck on all ota like

    o6994g0004o  XY76 0 pending_burntool neb://ipp053.0/gpc1/20141203/o6994g0004o/o6994g0004o.ota76.fits	
    

  • 19:10 registration finally caught up..
• 20:00 MEH: starting ippsky/staticsky processing in place of stdlocal as SAS has priority -- attempting to balance after skycal finishes to try and finish SAS by morning w/o impacting nightly processing
  • skycal finished, fullforced doesn't seem to be running after 20 mins.. -- c2 off, leaving 2x x2 on in case something happens
• 20:10 MEH: manually adding ipp067 and ipp072 to summitcopy to test, red and data blocked so if crash will minimize cleanup..
• 21:05 MEH: ippmd run, stdlocal run, watching load -- stdlocal turn off all x0,x1 so ~135 jobs running (ippmd ~170 jobs) -- BUT this is w/o diffims being done in stdsci apparently..
• 23:45 MEH: no WW diffs for MOPS being made.. -- 3 chunks available and nothing being queued.. -- CZW noticed initday not run today due to downtime, when added diffims now queued
• 00:30 MEH: warp faults -- cannot build growth curve (psf model is invalid everywhere)

• 01:00 MEH: nightly processing seems to have screeched to a halt -- ipp060 is terrible wait_cpu state

Wednesday : 2014.12.03

Thursday : 2014.12.04

Friday : 2014.12.05

Saturday : 2014.12.06

• revised -- planned downtime MRTC-B 590B Lipoa Automatic Transfer Switch (ATS) -- Saturday December 6th. They will be starting our shutdown processes at 9am and will hopefully start turning things back on at 3pm.
  • all processing stopped before ~7am
  • Haydn on site to start power down of systems @7am
