Raid 1 Failure - Rebuild or Delete
Raid 1 failure this am. I have two WD 1T drives in a raid 1 aray. the Intel storage manager reports the status as "Rebuild" with one drive status = "SMART Event(0)" in yellow and the other as "Member Disk(0)" in green.
(See attached screen pic)
The options are 1. Create RAID Volume or 2. Reset Disks to Non-RAID.
There is a notation at the bottom of the screen "Volumes with a REBUILD status will be rebuild within the operation systyem."
First time problem. Not sure how to proceed to insure no data loss. I have an online backup for data but not system files. Logic would tell me to select option 1 and let it rebuild the problem drive if it is not trashed. Not sure the remaining drive will be usable if I select Reset to Non-Raid. Thinking I should just replace the bad drive and let the storage manager recreate the Raid Volume. What to do????

I would try rebuilding with the questionable drive. The system will use the green(good) drive as the master. Give it time to rebuild and if you can take the system out of production for a time to allow the rebuild that would be best.
Master is a poor term. Should say 'updated' or 'current'

That appears to be the safest option. The bad drive had the "Smart Event" notation. Thought that might indicated that it just had a bad sector but would be usable after the rebuild. I have ordered a replacement drive.

Got it. New drive just arrived. Is there a user guide that provides these codes etc.
Refer to RAID controller documentation. There could be otherwise it should resend you to HDD vendor documentation as the SMART error is reported by HDD itself to RAID.
