[Linux-cluster] Clustered filesystem questions for shared storage on CentOS/vmWare/SAN

I used to use GFS for a while, but it has several requirements and some make it very inflexible. 
These days i'm all for GlusterFS (www.glusterfs.org) Gluster is a distributed filesystem, recently adquired by Red Hat. Gluster provides the main benefit of GFS, Cluster Filesystem, but without so many constrains.
