     5== February 10 (Haydn) ==
     6 - ippdb03 - corrected a misconfiguration in the ACS16, which caused me to accidentally remove power from it last night.  Gavin fixed the fsck problems today, mounted the 2TB MySQL RAID, and started it rebuilding.  It should work now.
     7 - ippc15 - unplugged it, so that it will stay off forever.
     8
     9== February 9 (Haydn) ==
     10 - ippdb03 - moved its disks to ippc15 (and decommissioned ippc15).  Now it should work reliably.
     11
     12== February 8 (Haydn) ==
     13 - ippdb03 - replaced the motherboard, SATA cables and 500GB drives, rebuilt Linux, but it still doesn't work reliably.  Probably the drive backplane is causing the problem.
     14
     15== February 5 (Haydn) ==
    516 - ippdb03 - tried a number of tricks to resuscitate /dev/sdb and boot from it, but none worked.  Finally replaced /dev/sda and /dev/sdb with tested 500GB drives, and reinstalled Linux from scratch.  However, it is taking to long to rebuild the new RAID, so I don't have much confidence it is going to work.
