------------------------------------
One final point. I would like to be able to monitor for suspect or failed
drives. Is my best bet to look at /proc/mdstat output and identify drives
which have been kicked out of the array? Or to monitor SMART variables (in
that case though I need to decide which ones are the most important to
monitor, and what thresholds to set)?
-------------------------------------------
For years I have used smartd without issues and it will log and email
anomalies as they occur.
It is also advisable to regularly "scrub" all md devices, to flush out
faulty sectors:
echo check > /sys/block/mdX/md/sync_action
See Documentation/md.txt for details.

Richard
