I'll get FC5 installed on a test cluster and try it out.

Yes, the access was simultaneous. If you have a specific test, (specific 
types of files or windows programs) I can try that too. I'm not denying 
that you're seeing problems with GFS+samba :-). If I can reproduce your 
problem, I can chase it down and we'll know why this is happening.

Looks like the openais component of the cluster is missing. The cluster 
architecture has changed quite a bit for GFS2. Please refer to this for 
help installing GFS2:
