I'm following the redhat docs. I do not have the gui. I'm confused about the fencing piece. It implies that fencing is required to allow a service to run on only a single node in a cluster which ensures data integrity. Makes sense if your data resides on ext3 or an equivalent. But it seems to defeat the purpose of GFS. In fact, I really only want to utilize gfs and don't want my app to be a service or eligible for failover. I basically want 3 nodes to serve data from the same filesystem. If an app/service/node crashes or fails it's fine, I'll still have 2 serving the same data via the same apps. So my questions are, how should I configure fencing? Are there aspects of the cluster I should/can leave out of the mix since I really only want gfs functionality, not ha functionality.
