Need help with Raid 5 problem on Areca 1220

[phoenix31tt]

Hi,

I have a raid 5 setup on an areca 1220 with a crazy situation and I need your help

The setup is attempting to rebuild the raid on the channel 2 device (because there is the red arrow on channel 2 in the httpgui console) I'm not sure why it is attempting to rebuild the raid on that drive as there was no device failure on that channel.

The problem is now that its attempting to rebuild I'm getting read errors on channel 4 device and the rebuild is stuck on 0% with 0 time elapsed and alot of read errors.

How do you guys suggest I proceed?

Please post the entire log from the card ASAP. Do you have a current backup of the contents of this array? Does it say Degraded or Failed in the status of the array? What brand and model are the drives connected to the card?

Hey thanks for the reply... I had organized to get a copy of my data from an off island source so i decided to go brave with my best logical method seeing as my data was inbound neways.

I did the following and it's now back up and running:

- Delete the raid set
- Rebuild the raid set exactly as it was
- Recreate the volume set with no init (at this point it was reading everything as normal, but i still had problems booting into windows as channel 4 was still giving major errors)
- Replaced the disk on channel 4 (at this point raid went into rebuild again and my volume set came back up fine i can now access the data)

my best guess is that the areca was detecting a need to rebuild drive 2 however drive 2 didnt actually need rebuilding, so I essentially canceled the rebuild and was able to replace the actual faulty drive.

Hope that makes sense...
