Brian, By now you have suggestions from smarter RAID-folk than me. I use an old server with a 3-drive RAID5 array. (I now use 2 hot spares!) My array has gone "degraded" 3 times in the past. In each case, replacing the 'suspect' drive has allowed the RAID controller to fully rebuild the array. I use an Adaptec 3200S (U160 SCSI) controller.
I do understand your confusion. I read that you are getting grossly conflicting information. I would focus on what your RAID controller says first. Replace the 'suspect' drive, and, allow your controller to do what it should know how to do. JMHO. PSU failures are a real PITA, right?............ :) Best, Duncan On 09/22/2010 06:20, Brian Weeden wrote:
Came home from a week of traveling to find my HTPC non-functional. Power supply failure. Swapped in a new power supply, and on reboot I get the dreaded constant error beep from my Areca 1220 RAID controller. And yep, the array is degraded. I have a 8 x 1 TB RAID 5 array. The RAID config software says that the drive on channel 4 failed and that the array is in a degraded state. But looking at the HW info screen, it correctly identifies the HD attached to channel 4 with all normal readings and stats as "free". All of my data is there but I am anxious to get the array back to a normal state before something else bad happens. How do I recover from this? I don't see any notification that it is rebuilding the array. If I hit "volume set check" it says there is no volume to check. It says I cannot expand the RAID set while the status is degraded. Do I need to "modify" the array to confirm it only has 7 drives now, and then expand it? --------------------------- Brian Weeden Technical Advisor Secure World Foundation<http://www.secureworldfoundation.org> +1 (514) 466-2756 Canada +1 (202) 683-8534 US
