The PVFS2 filesystem at /mnt/pvfs2 appears to be correctly configured.
Copying files to /mnt/pvfs limited by network, so OK.
Did a high IO-demanding muxing of audio/video first locally and then on
/mnt/pvfs2 both from the same machine which is one of the data servers.

What could be the reason it is, like it is.
