Haven't followed the entire thread, but wanted to point out something
important to remember. SMART is not a reliable indicator of failure.
It's certainly better than listening to it but it picks up less than

Hi Matthew,
I'm running 7.2-RELEASE-p4 on an i386 HP server (ML G5) in RAID1
configuration. Very recently, I've seen IO errors such as:
ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=20472527
reported and the RAID mirror is now offline.
ad0: TIMEOUT - WRITE_DMA48 retrying (1 retry left)
Hi there,
I'm running 7.2-RELEASE-p4 on an i386 HP server (ML G5) in RAID1
configuration. Very recently, I've seen IO errors such as:
ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=20472527
reported and the RAID mirror is now offline.
ad0: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=
