The Filesystem resources, such as server0_fs, are used to describe the shared storage block devices that serve as back end storage for PVFS. This is where the PVFS storage space for each server will be created. In this example, the device names are labeled as label0 through label3. They are each mounted on directories such as /san_mount0 through /san_mount3. Please note that each device should be mounted on a different mount point to allow multiple pvfs2-server processes to operate on the same node without collision. The file system type can be changed to reflect the use of alternative underlying file systems.
