The file /sys/block/mdX/md/sync_action can be used to issue a recheck of
the data. Read Documentation/md.txt in kernel source for details about
the exact procedure. My advice (if you still want to continue using
software raid) is that you run such a check before any add/grow or other
action in the future. Also, if the raid has been unused for a long while
it might be a good idea to recheck the data.

I feel your pain. Massive data loss is the worst. I have had my share of
crashes. Once due to bad disk and no redundancy, the other time due to
good old stupidity.
