3w-xxxx: scsi0: AEN: ERROR: Drive error: Port #6. 3w-xxxx: scsi0: AEN: WARNING: Sector repair occurred: Port #6.
I do not now if 3ware sets some block asside when the raid is created for use when errors occure or if they justs writes the block agan and the disk does the realocation by it self.
The downside of using 3ware raid5 is that performance is quite much lower than with md, with 8 disks I get 90MB/s with md and 40MB/s with 3ware in writespeed.

Hi, I am running a server with Linux software-raid (3ware controller). But from time to time, a disk is kicked out by md. This will happen when 3ware card reports a unrecovered read error for a sector. But when I run raidhotadd, the disk can added back to raid with no problem. So my questions are: (1) Will md kick out one disk if it find out ONE bad block? (2) Is it possible to set up a threshold, only the amount of bad blocks pass this threshold, the disk will be kicked out. (3) Is it possible to remap the bad blocks to some spare blocks automatically on the fly?
Thanks!
