As you can see in the log, the write error recovered with auto reallocation! As I understand it, this is a normal event with today�s disks. I don�t think the disk should have been considered failed. Comments please?
You need to talk to linux-scsi about this. The scsi subsystem told the raid subsystem that there was an error, so the raid subsystem stopped using the device. If the write error was recovered, scsi shouldn't have reported an error to raid. NeilBrown
