I have two hot spares in the server, and I'm happy to engage them, but I don't understand what it would do with that information in the current state it's in.Ĭan I pull out the drive that is demonstrably failing (the WARNING drive), when I have two DEGRADED drives in a RAID-6? It seems to me that the best scenario would be for me to pull the WARNING drive and tell it to use one of my hot spares in the rebuild. How do I get it to start actually rebuilding? This particular controller doesn't appear to support /c2/u1 resume rebuild, and the only rebuild command that appears to be an option is one that wants to know what disk to add ( /c2/u1 start rebuild disk= according to the help). U1 RAID-6 REBUILDING 4%(A) - 64K 7450.5Įxamining the SMART data on the three drives in question, the two that are DEGRADED are in good shape (PASSED without any Current_Pending_Sector or Offline_Uncorrectable errors), but the drive listed as WARNING has 24 uncorrectable sectors.Īnd, the "rebuild" has been stuck at 4% for ten hours now. Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) After getting to about 4%, it got ECC errors on a third drive (this may have happened when I attempted to access the filesystem on this RAID and got I/O errors from the controller).
This morning I came in the office to discover that two of the drives on a RAID-6, 3ware 9650SE controller were marked as degraded and it was rebuilding the array.
