[hobbit] Use clientchannel to determine status of /proc/mdstat on hobbit server?

[Charles Jones]

A someone kludgey way to do it could be to monitor /proc/mdstat just as 
if were a normal file, and setup Hobbit to monitor it just like you 
would /var/log/messages, triggering on a pattern matched error string. 
This would allow you to have it setup server-side like you want.

Not the best solution, I know, but it popped into my head :)  You could 
also configure mdadm on the client machines to send an email where there 
are RAID issues.
