Could you try to do a "make clean" and rebuild one more time to make sure?
If that doesn't work, then it might be best just to send me a tar.gz of
your source tree and configuration files (off of the mailing list) so I
can have a look at what's going on. I'm not sure why you would still
hit that error.

Ok , the patch does the job- in modifying the code correctly that is.
I see the bug in the code and I see that the patch fixes it. However,
the problem still persists.
The error is similar as well:
[D 14:05:40.412091] PVFS2 Server version 1.5.1 starting.
[E 14:05:40.422537] Error: /home/thacker/etc/pvfs2-fs.conf line 47:
Option can't be defined in that context[E 11/05 14:05] Could not find
handle range for host (null)
[E 11/05 14:05] Please make sure that the host names in
/home/thacker/etc/pvfs2-fs.conf and
/home/thacker/etc/pvfs2-server.conf-node15 are consistent
[D 11/05 14:05] PVFS2 Server: storage space created. Exiting.
Cannot find handle range? Seems to be fine without the Distribution
sub-section
Does the order in which these subsections appear matter ? I've jus added
them right after the default <StorageHints> subsection

Hi Phil,
Yes I have the patch in the extracted directory of PVFS2-1.5.1 and I
apply the patch using
patch -p0 < patch
Although the patch succeeds, I still face the issue.
I have been going through the code too , since the patch only modifies a
single line.
For one the patch begins at line 1248, but line 1248 in pvfs2-1.5.1 has
something entirely different. I still dont understand though, how the
patch succeeds
For another, I think the patch refers to the function
DOTCONF_CB(exit_distribution_context) which is at line 1039 in my
server-config.c . I modified the configuration context there to
CTX_FILESYSTEM as does the patch, but the problem persists.

Are you sure that you applied the patch correctly? That fixes the
problem when I try the same scenario here.

The patch did not help either. It brings up the same error.
Could there be more patch releases which I can try?

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:

Phil:
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!
