[Pvfs2-developers] Does this look right?

[Scott Atchley]

Hi all,

Both pvfs2-ping and pvfs2-statfs seem to be working. Does everything  
below seem reasonable?

Thanks,

Scott


% pvfs2-ping -m /mnt/pvfs2

(1) Parsing tab file...

(2) Initializing system interface...

(3) Initializing each file system found in tab file: /etc/pvfs2tab...

    PVFS2 servers: mx://fog33:0:3
    Storage name: pvfs2-fs
    Local mount point: /mnt/pvfs2
    /mnt/pvfs2: Ok

(4) Searching for /mnt/pvfs2 in pvfstab...

    PVFS2 servers: mx://fog33:0:3
    Storage name: pvfs2-fs
    Local mount point: /mnt/pvfs2

    meta servers:
    mx://fog33:0:3

    data servers:
    mx://fog33:0:3

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

    meta servers:
    mx://fog33:0:3 Ok

    data servers:
    mx://fog33:0:3 Ok

(6) Verifying that fsid 1318064247 is acceptable to all servers...

    Ok; all servers understand fs_id 1318064247

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

    Root handle: 1048576
      Ok; root handle is owned by exactly one server.

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

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



% pvfs2-statfs -m /mnt/pvfs2

aggregate statistics:
---------------------------------------

         fs_id: 1318064247
         total number of servers (meta and I/O): 1
         handles available (meta and I/O):       4294967290
         handles total (meta and I/O):           4294967294
         bytes available:                        23916113920
         bytes total:                            28573982720

NOTE: The aggregate total and available statistics are calculated based
on an algorithm that assumes data will be distributed evenly; thus
the free space is equal to the smallest I/O server capacity
multiplied by the number of I/O servers.  If this number seems
unusually small, then check the individual server statistics below
to look for problematic servers.
