General :: No Automatic Rebuild Of RAID 5 After Replacing Bad DiskDec 12, 2009
I have a 5 disk raid 5 array that is composed of SATA A:0,1; SATA B: 0,1, and SATA C:0, and one of the disks (SATA A:0) recently went bad on me. I have an ICP raid controller that is about 5 years old. I replaced SATA A:0. After rebooting, I went into the controller and verified that it saw the disk in the hard-disk info section...there I noticed that in the "status" section, that the SATA C:0, SATA B:1 disks were listed as being "in array", the SATA A disks were blank, and the SATA B:0 disk was listed as "fragment". When I go into the "repair array" section, the controller tells me that there are no arrays that are in failure, error, or need to be rebuilt.
This puzzles me, as I thought the controller would know that the array needs to be rebuilt after replacing the disk and I don't see a way to initiate a rebuild. If I just let the server boot after replacing the disk, then I get back that there are the correct number of disks in the raid 5 and that it is ready, however, the screen then goes blank and I get a blinking cursor and the system seems to hang. There are no activity lights on any of the drives associated with the raid 5, which makes me think that the system is not rebuilding the array at this point.
