FYI: There was a bug in PVFS expressed with many clients simultaneously opening the same file with O_CREAT. In some instances more than one client would receive a successful response from the metadata server, resulting in odd behavior depending on the application, such as writing to the wrong datafile handle. The attached patch (applied to 2.6.2) should fix this bug. The bug only affects PVFS versions 2.6.0 - 2.6.2. If your use of PVFS includes the workload described, you should applied it.
