This was a bug in our older releases. You can try applying this patch
to fix it if you are still stuck on 1.5.1:

I did add the Distribution context to my pvfs2-fs.conf , and restarted
the server nodes, and received an "Option cant be defined in that
context" error.
The error points to the Filesystem context, maybe indicating that I
cannot declare the distribution sub-context here (?)
I have attached the error and a copy of my pvfs2-fs.conf
The error comes up when I create a storage space.
[I have 4 storage servers and 1 MDS. I tried by reconfiguring storage
and restarting the servers and the error persists. It also says that the
host names must be consistent [see log] . Thats strange since otherwise,
the servers start fine, without the Distribution context defined]

Hi Nirmal,
I think that you can use the same mechanisms to set distribution
parameters in 1.5.1 as in our newer releases.
There is some information here about how to set the strip size at run
time for a particular directory (no need to recompile):
http://www.pvfs.org/fisheye/browse/PVFS/doc/pvfs2-tuning.tex?r=1.2#l208
You can also set a default for the whole file system in your server
configuration file by adding a section that looks like this into your
<Filesystem> section:
<Distribution>
Name simple_stripe
Param strip_size
Value 4194304
</Distribution>

Hello
I am using PVFS2-1.5.1 and as far as I know, to modify the default
stripe size of PVFS2, I must modify the header
include/pvfs2-dist-simple-stripe.h .
Strangely , I did so and rebuilt the source, yet the pvfs2-viewdist
still shows me the default striping for any new files created with the
modified pvfs2 build!
