rocketraid RAID 5 Failing to rebuild
Posted on 2009-02-19
I have a system where the E drive is a RAID5 array of 4 1TB Seagate hard drives. The drives are connected to a Highpoint RocketRaid 2310 controller. I got an email from it saying that "Disk 'ST31000340AS-9QJ21HC4' at Controller1-Channel3 failed" then a few hours later i got another few emails saying "error occured on the disk at 'ST31000340AS-9QJ0N0FA' at Controller1-Channel2".
What I did was shut it down and unplugged the channel 3 hard drive and rebooted to confirm that the virtual drive was still accessible without it so that I knew I had the right drive for channel 3. Then I replaced that drive with a new one. The Raid BIOS prompted me to add it to the array. Then, in windows, I used the management utility to initialize the new drive and the array rebuild process started. It ran for a few hours and then at about 85% it started throwing multiple errors like "". Then after I clicked a few of those I would get a message that it "Successfully repaired bad sector on disk 'xxx' at Controller1-Channel2. Last I get a message that the Rebuild failed. Then it starts to rebuild again and the cycle continues.
In the Array view of the management software there is still a padlock icon beside the drive at channel 3.
I can still access my data and have copied it off to an external drive. Im thinking that the channel 2 disk has physical problems that prevent the controller from ever rebuilding the array, and because i just replaced the channel 3 disk that I cannot now replace the channel 2 disk. Do I have it right? Any ideas for how I can save the array?
