I'd stay away from Gluster for home directories... too many small
files. The performance drops dramatically. I used gluster for virtual
machines images, and performance was good.
My solution for syncing home directories turned into using Bittorrent
Sync. Replication isn't immediate, but it's fast enough. I also
decided to sync only a single directory and not the whole home dir.
That way, as a user, I could specify what I wanted to sync and what I
didn't. For example, one machine has a huge downloads directory. No
use syncing that to my Mac laptop.
