Murali,
I just found out that the pvfs-viewdist.c I got from a link posted in the
pvfs2 user mailing list:
http://www.beowulf-underground.org/pipermail/pvfs2-users/attachments/20051118/27e54a5c/pvfs2-viewdist-0001.bin
is different from the one attached in your email earlier. This is the one
causing all my problem.
After trying your copy, my problem is solved. Here is an output:
% pvfs2-viewdist -f /pvfs2/wkliao/testfile.dat
dist_name = simple_stripe
strip_size = 65536
Number of datafiles/servers = 4
Server 0 - tcp://c3:3334
Server 1 - tcp://c4:3334
Server 2 - tcp://c1:3334
Server 3 - tcp://c2:3334
Thanks a lot.

Hi Wei-keng,
I couldn't reproduce this on any of my setups.
Could you upgrade pvfs2 to the cvs version and see if the problem
persists?
The viewdist program prints out "Not a meta file" if the getattr call
indicates that the given path name is not a file. Alternatively,
could you try mounting the PVFS2 file system and then run the same
viewdist program and see if you get similar errors?
Thanks,
Murali

Murali,
I got a compilation errors complaining about:
error: attr/xattr.h: No such file or directory
warning: implicit declaration of function fgetxattr
warning: implicit declaration of function Ld
After commenting out xattr and adding define for Ld, it linked OK,
but when I ran it, an error message said
% pvfs2-viewdist -f /pvfs2/wkliao/testfile.dat
Not a meta file!
Could not open /pvfs2/wkliao/testfile.dat
but
% pvfs2-ls -l /pvfs2/wkliao/testfile.dat
-rw-r--r-- 1 wkliao users 262144 2005-12-02 15:39 testfile.dat
I am using pvfs2-1.3.1.

Hi,
Does the pvfs2-viewdist.c program work for you?
Do let us know,
Thanks,

I am running a few I/O benchmarks by exercising different stripe sizes on
PVFS2. For each stripe size, I change
PVFS_DIST_SIMPLE_STRIPE_DEFAULT_STRIP_SIZE and rebuild PVFS2.
I need to verify the stripe size of a newly-created PVFS2 file.
Can someone provide such a utility? (pvfs2-stat supposes to but does not
provide such info.) Thanks.
