I'll just respond to myselft in part. I beleive that using gfs2 in a cluster environement is safer in the event that a filesystem would be mounted on several node, for whatever reason. Am i right ?

Another question in that regards, as for the number of journal to create to a gfs filesystem. Do I need a journal per node or per node that will use the filesystem ?

Thanks again,
Nicolas
