[Gluster-users] Sharing home directories between two symetric nodes?

[Keith Freedman]

I think you have it right.
it's an interesting way to use gluster..  you run a risk on occasion, however.

if you happen to update files on both ends while they're 
disconnected, then once you're re-connected, when you access the same 
file, you can not be sure which version will prevail.

(you can, but it's difficult to know--as I understand it, gluster 
tracks a timestamp and a revision number--somehow it uses these to 
decide which file is "newer")

Also, gluster doesn't to automatic healing--meaning, when you 
reconnect it doesn't immediately push the updates to the other side.. 
this is done only when files are accessed.  So, if you make file 
changes while disconnected, and then reconnect.. change some OTHER 
files, then disconnect again, you may still have an older version of 
the original file

those are my thoughts,
Keith
