I guess you are the first to try.

It looks like pvfs2 doesnt support fsync on directory inodes. Im not familiar 
with pvfs2, and I couldnt confirm this with a quick googling.

The option [posix]/dirsync in the configuration file will turn off fsync of 
directory inodes, and should get you up and running. This was added in 
version 1.1.13. (If you dont want to upgrade, just comment out the call to 
fsync in the sync_directory function). 

This may or may not affect ACID characteristics of your storage.
