I recently added a 6th disk to a RAID5. All disks are WD 320GB SATA, of different
Caviar models (SE, RE) and this new one is RE16.
It worked well for about 5 days (completed a 20 hour grow OK). I now see the following
messages logged (see at end). Can someone explain what it means? The raid5 is still
up and it did not react to this. Being a mythtv repository it gets used regularly.
Is this a disk issue? A controller issue (the new disk is now the fourth on a
Promise SATA-II-150-TX4)? A kernel problem (2.6.20 vanilla).
