PS1 IPP Czar Logs for the week YYYY.MM.DD - YYYY.MM.DD

(Up to PS1 IPP Czar Logs)

Monday : 2014.09.15

• MEH: until the new consortium starts (10/2014?), all WS diffims to be turned off -- comment out label and turn off query to create in stdsci auto-startup, sending all to cleanup
• 13:40 MEH: Gene asked for pv3 stdlocal stack poll bump to 200 and adding in more data nodes for processing -- adding 4x ippsXX for ~60 for now since they are unused (easier to deal with when nightly starts)
  • ipp058 getting hammered when trying to clean up ~1TB of test processing -- putting into repair for now
  • same for ipp060, both have a nice chunk of space available again
• 16:00 MEH: adding 1x s3 manually to lanl stdlocal -- notice many in ignore_s3 running, so the auto on/off script not properly turning off??
  • cleanup still running, if too much loading, will just take that much longer -- adding 1x s3 see clear increase in cleanup time for jobs
• 20:15 MEH: ipp058 behaving badly.. console login up, but get errors -- may need to power cycle

  Cannot execute /bin/tcsh: Too many open files in system
  
  login: failure forking: Cannot allocate memory
  

  • finally cleared some after a bit and neb-host down -- many many [2014-09-15 20:27:07] VFS: file-max limit 4945516 reached
• 20:45 MEH: unclear if gpc1 down for the night, but lanl stdlocal should be fine w/ ippsXX added at least
• 21:30 MEH: nightly started, ippsXX off in lanl stdlocal, ipp058 heavy load so into repair until morning
• 22:00 MEH: seeing file issue faults in warp stage for ipp060 -- also repair until morning -- may not be robust enough with so few data nodes available

  Unable to perform warp.
   -> psFitsOpen (psFits.c:217): I/O error
       Failed to delete a previously-existing file (/data/ipp060.0/nebulous/e4/40/5106938020.gpc1:OSS.nt:2014:09:16:o6916g0050o.795035:o6916g0050o.795035.wrp.1030977.skycell.1140.098.mask.fits), error 2: No such file or directory
   -> pmFPAfileOpen (pmFPAfileIO.c:816): I/O error

       failed WRITE in FPA_AFTER block for PSWARP.OUTPUT.MASK
   -> pswarpCleanup (pswarpCleanup.c:84): I/O error
       Unable to write files.
  

  • also seeing warp stage log having issue log warning with new keyword (Unable to find (null) --- assuming UTC), will need to clean up
• 22:10 MEH: stdsci having timeout flurry for chiptool -pendingimfile.. ippdb01 has load ~13 -- taking out all extra labels (CNP,STD,PI,ps_ud_*) -- seems improved
• 22:30 MEH: even large load on apache servers (ippc0x), lanl stdlocal stop for now until nightly starts moving along faster
• 23:10 MEH: no access to ganglia -- looks like ippops2 rebooted, forget if know how to restart -- Gavin notes

  # restart ganglia monitor
  /etc/init.d/gmond restart
  # restart gmetad web frontend
  /etc/init.d/gmetad restart
  

  • ipp svn/wiki also down -- wasn't ippops2 but ipp002 crashed -- back up once Gavin rebooted. Will look at possible UPS/PDU issues since it wasn't under any load
• 23:50 MEH: lanl stdlocal set to run but w/ only ~100 nodes -- nightly processing is slower than normal and possible hampered by lanl stdlocal, but if weather comes in at leas some processing done

Tuesday : 2014.09.16

• 06:30 MEH: ipp036 crash ~0618, nothing on console -- power cycled
• 06:35 MEH: lanl stdlocal stop until nightly finished, nothing loaded anyways
• 09:30 MEH: lanl stdlocal back run, +4x ippsXX back on, +1 s3 back on, stack.poll 200, ipp058+060 up from repair, regular stdsci restart w/ ps_ud_* labels back in
  • again, auto-on for storage nodes turning ipp060,064 and other ignore ones on in lanl stdlocal
