Resync raid drives

[Chris Mason]

I ended up using a similar plan, I installed and used mdadm to do the same
thing. It worked great.

I need to know in the future if my RAID devices are out of sync, and I don't
think mdadm is up to it, what do you suggest? It does seem all I have to do
is:

# nohup mdadm --monitor --mail=sysadmin --delay=300 /dev/md0 &

But I was looking for something more finished. However, this should work
also.
