Issues

  • For some reason, upgrading the kernel to the 2.6 series causes the web files in AFS-space to hang after a while. Neither the cause nor a solution for this has been found yet.

MegaRAID

Adelie's drives utilize a hardware RAID-5 setup with a MegaRAID card. If you hear a slow beeping in the machine room, it is most likely the MegaRAID card alerting you to a failed drive. You can use the megamgr utility to rebuild the failed drive (located in /root/megaraid/megamgr as of the time of this writing). You can also add another drive as a hot spare to keep the old drive in, but use another drive to rebuild the array. Currently, the drive in ID 1 keeps failing, so a new drive in ID 3 is being used as a hot spare.
