Services Unit July 2019 Power Work

Things we want to do while the power is off, or just after it comes back, to the Forum Server Room.

  • move gresley (to rack 4) and peppercorn (down a U) (to leave space for possible riddles JBOD) - ForumRackPopulation
  • install JBODS below gresley and peppercorn
  • attached 4TB JBOD to ifevo2, probably shuffle boxes to make cabling neater - ATABoxesInfo
  • kraken is reporting a fan 3 has failed. Swap one from nessie or yeti.
  • upgrade afsdb from AFS 1.6 to 1.8 - It will be a version of the last UpgradeAFSDBPlan
  • SL7.6 all off machines - probably switch profiles on the Friday so they only have the onboot RPMs to do on restart.

To do before the power off, probably Friday afternoon.

  • Switch printing to borges - DONE
  • Switch www-dr to be the live www.inf - ServiceUnitWwwOffsiteDrPlan (notify any recent CVS publishers)
  • Remove the #define DICE_STICK_WITH_SL75 from the list of machines below. LcfgStop is probably useful - DONE

After the event notes

  • ifevo2 needed fixing following shuffle and attachement of extra jbod
  • crivvens (bpweb) /home/UUN stopped working
  • ranter (jabber) room service doesn't start automatically, manually OK
  • gresley a RAID disk member failed
  • Need to tidy/fix printer dhcp/gateway - should use infrastructure machines for DHCP and routing, so no network dependency on cups server
  • general lack of some IPv6
  • huldra tibs DRIVE IDENT error
  • quotas needed restarted on gype and bahookie (they powered up before quotas host)
  • some servers needed extra reboot as they were up before package server was responding (ie SL7.6 didn't happen)
  • buckrogers RPM clash (SL7.6 related)
