Can GFS used without clustering
I would like to know if GFS can be used without clustering.
That is, I would like to use GFS only as a file system to have multiple hosts access some shared file system. GFS probably has a lock manager that guarantees mutual exclusion between readers and writers. However I don't want to use the clustering capabilities of Linux (Red Hat Cluster Suite).
Also I would like to know if GFS allows multiple readers / single writer mode of operation. This mode of operation is much less expensive than multiple readers / multiple writers mode of operation.
Thank you in advance,
