[Pvfs2-users] IOR 2.10.2 on PVFS2 1.5.1

[Nirmal Thacker]

I have now built mpich2 1.0.7 for PVFS2
Now I face an error while running the IOR test.
I have attached the log . The test fails to "open a file" at the PVFS2
servers

I have a workaround which Im not very pleased with.
I first pvfs2-touch a file- hence creating one for the test

#pvfs2-touch /mnt/pvfs2/test.001

And then I run the test:

#./IOR -a MPIIO -k -o /mnt/pvfs2/test.001

This works fine - without errors

As you can see its not very elegant. Moreover this would not allow me to
say, obtain some metadata numbers like file creation time [if this could
be possible in IOR]
Moreover, I observed that while I can see notable difference in
bandwidths when I transfer a larger file, I do not see this reflecting
in the file size.
The pvfs2-ls -lh shows me an empty file

Anyone got their 2 cents to offer? :-)
