Hi all,
pvfs2-cp and pvfs2-rm are working as well. I copied a 256 MB file to
PVFS and then back to a different filename. Diff reports that they
are identical.
I have also tried pvfs2-stat, pvfs2-ls, pvfs2-lsplus, and pvfs2-
viewdist.
While copying the large file, I see a lot of expected messages arrive
before the matching receive has been posted. I believe Sam or RobL
mentioned that if there are multiple messages per operation, that the
next receive is not posted until the previous receive is completed.
Is that correct? If so, would it be possible to post all at once or
would that break some of the other BMI methods?

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

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

aggregate statistics:
---------------------------------------
fs_id: 1318064247
total number of servers (meta and I/O): 1
handles available (meta and I/O): 4294967290

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.
