I am using an ASUS P5Q-Pro motherboard with the ICH10R chipset and 4 320GB hard drives in RAID 5. After an issue with a faulty partially connecting modular power supply connector which fed all the hard drives, I'm left with 3 OK drives but the array showing FAILED. All hard drives are physically working 100%.
This is what the Matrix storage manager said before the incident.
Array 001 (RAID 5), NORMAL
Port 5 Drive 4 NORMAL
Port 4 Drive 3 NORMAL
Port 3 Drive 2 NORMAL
Port 2 Drive 1 NORMAL
Non-RAID Drives
Port 0 Non-RAID (boot drive not part of array)
After:
Array 001 (RAID 5) FAILED
Port 5 Drive 4 NORMAL
Port 4 Drive 3 NORMAL
Port 3 Drive 2 NORMAL
Missing
Non-RAID Drives
Port 2 Drive 1 OFFLINE (listed as member of Array 001 but OFFLINE)
Port 0 Non-RAID (boot drive not part of array)
Considering 3 of 4 drives are listed NORMAL array members, the array should be DEGRADED not FAILED.
Following some internet forum advice for a similar situation I removed Drive 1 from the array in the hope of changing FAILED to DEGRADED to let me salvage data off it but instead I now get
Array 001 (RAID 5) FAILED
Port 5 Drive 4 NORMAL
Port 4 Drive 3 NORMAL
Port 3 Drive 2 NORMAL
Missing
Non-RAID Drives
Port 2 Non-RAID (not OFFLINE but not part of array)
Port 0 Non-RAID (boot drive not part of array)
Stubbornly, the array is still listed as FAILED.
Notes: There was no option to mark Drive 1 OK after it came up as OFFLINE. The entry Missing contains no information. As at September 14, the latest 1304 motherbord BIOS is installed and most recent Matrix drivers/utility is being used. Data should be OK as the drive was not being written to when the power supply issue struck. It would appear the RAID array's meta-data is corrupt in some way.
Is there a way to force Array 1 to DEGRADED status using the 3 of 4 array drives marked NORMAL? Is there any other way to access data on the array or rebuild it?
