This is for running some "cloud" servers where we want all files available on each machine locally so all servers have the same files but can still get local performance. I don't think I'll need to run a cron like that but it's not my network so I'm trying to figure out how to get all of the gears working together. 

I did just discover that changing permissions does not seem to heal. I had two servers up, killed glusterfsd on server2, on client I changed the permissions of a file, brought server2 back online, ran ls on client, and server2 still had the old permissions. It's not really a big issue since I don't see myself changing permissions often, esp with any servers down, but interesting nonetheless.
