[Linux-cluster] failover questions after upgrade

[jason at monsterjam.org]

woohoo. I wrongly had ext3 in my cluster config as you said. 
removed that, removed that whole fs line so that the cluster would not try to 
mount it.. Mounted the /mnt/gfs from my /etc/fstab like the faq said.. 
restarted everyone and now things work exactly as expected.
thanks Lon!
