PVFS2 currently includes (among others) the following tools for manipulating the file system using the native PVFS2 library: pvfs2-ping, pvfs2-cp, and pvfs2-ls. These tools check the health of the file system, copy files to and from a PVFS2 file system, and list the contents of directories, respectively. Their usage can best be summarized with the following examples:

bash-2.05b# ./pvfs2-ping -m /mnt/pvfs2

(1) Searching for /mnt/pvfs2 in /etc/pvfs2tab...

   Initial server: tcp://testhost:3334
   Storage name: pvfs2-fs
   Local mount point: /mnt/pvfs2

(2) Initializing system interface and retrieving configuration from server...

   meta servers (duplicates are normal):
   tcp://testhost:3334

   data servers (duplicates are normal):
   tcp://testhost:3334

(3) Verifying that all servers are responding...

   meta servers (duplicates are normal):
   tcp://testhost:3334 Ok

   data servers (duplicates are normal):
   tcp://testhost:3334 Ok

(4) Verifying that fsid 9 is acceptable to all servers...

   Ok; all servers understand fs_id 9

(5) Verifying that root handle is owned by one server...

   Root handle: 0x00100000
   Ok; root handle is owned by exactly one server.

=============================================================

The PVFS2 filesystem at /mnt/pvfs2 appears to be correctly configured.
