Hi Shailesh,

If your storage is not shared, what exactly do you mean by "used
collectively"?

You can use the cluster suite to cluster a bunch of PCs together
so they cooperate, provide High Availability services (through
rgmanager) and so forth, regardless of whether you use GFS.

If your storage isn't shared between the systems, you don't
need GFS.
