• 08:05 MEH: remaining few nightly science exposures finishing up
• 09:38 Bill: ippc03 is running out of space in /tmp. The nebulous_server.log file had grown to 22G. Stopped apache, moved the file out of the way, restarted apache, then deleted it.
• 11:10 MEH: ipp05,08,09 nebulous_sever.log >22G as well, leaving ~4G on / OS disk and should be cycled out as well -- done. ippc07 will be next, only ~9G left available
• 19:00 MEH: MD09 deepstacks done so compute3 back to stdsci and stack until start MD08 refstack ~tomorrow
• 22:20 MEH: appear to have lost connection from ifa to production cluster? ganglia also reporting all systems down..

• 07:00 MEH: network issue with summit, but also something odd with production cluster and looks like some systems are down and some were rebooted.
  • still down: 028,033,036,046,048,c17,c19,db02 and console not reachable -- was ganglia problem for some, ipp046,048,c17,c19 actually down/off network, cannot connect via console
  • checking if the stsci nodes were power cycled -- no, so probably good thing
  • ippdb00,01,03 have been so may need to check mysql
  • various data (non-stsci data) nodes have been rebooted it seems
• 08:30 MEH: restarted screens and czarpoll on ippc11, will wait for roboczar until systems back running
• 08:40 MEH: rebooted ipp036 to fix mount issues, didn't come back up cleanly after whatever happened last night. need to scan mounts on all machines
  • serge put ipp036 into neb-host repair -- need to put back up - ok
  • ipp028,033,036,060 disks aren't always mounting -- Gene noted ypbind gone rogue, need to kill and restart with nfs (sudo tcsh, su - otherwise once kill ypbind no sudo access of course)
  • some wave1 machines trouble mounting wave4
• 09:30 MEH: ganglia is showing several machines high 1-m load but nothing running, gmond probably needs to be restarted on most/all machines -- done, and login seems fine except for ipp041 date below
• 09:40: MEH: ippc17 and ippc19 down, ippRequestServer (pss, datastore db and replication) so not possible for PSS to run until fixed
• 10:00 MEH: ipp041 date is wrong -- 10:25 manually set to w/in 1s. how to fix time sync?
• 11:45 MEH: ipp048 and ippc19 still problems, ipp048 to down. -- Haydn and Rita having trouble logging into ipp048 console, I can log in and disk scan taking the time for reboot -- back up now, neb-host up.
  • ippc19 still being investigated
• 12:05 MEH: datanodes back online, mounts appear fine. slowly starting pantasks -- summitcopy, registration, stdscience
