Just providing a little more followon information...

I have had a further 52 of these messages over the last day. No obvious
cause.
Mar 22 13:14:55 haze kernel: ata2: no sense translation for op=0x28
cmd=0x25 status: 0x51
Mar 22 13:14:55 haze kernel: ata2: status=0x51 { DriveReady SeekComplete
Error }

Most recently this happened:

Mar 22 13:47:09 haze kernel: ata2: no sense translation for op=0x28
cmd=0x25 status: 0x51
Mar 22 13:47:09 haze kernel: ata2: status=0x51 { DriveReady SeekComplete
Error }
Mar 22 13:47:09 haze kernel: sd 1:0:0:0: SCSI error: return code = 0x8000002
Mar 22 13:47:09 haze kernel: sdb: Current: sense key: Medium Error
Mar 22 13:47:09 haze kernel:     Additional sense: Unrecovered read
error - auto reallocate failed
Mar 22 13:47:09 haze kernel: end_request: I/O error, dev sdb, sector
396518289

with dmesg piping up with:
raid1: sdb2: rescheduling sector 5801424
raid1: sdd2: redirecting sector 5801424 to another mirror

no drives were kicked from the array.
