Hi.<br><br><div class="gmail_quote">I installed pvfs2-2.8.3 and mpich2-1.3.2 on Debian 5.0.6. Our pvfs2 installation was verified using pvfs2-{ping,cp,ls} as mentioned in the manual. Also, mpich2 installation passed the 'make testing' verification on the nfs filesystem. But, the io section of 'make teting' procedure, fails on pvfs2 filesystem. Only four tests: test/mpi/io{getextent,i_noncontig,async,userioerr}, passed without error. Even more test/mpi/io/async_any produces error messages on the pvfs2-server.log as:<br>

<br>=============================================================<br><br>The PVFS2 filesystem at /pvfs appears to be correctly configured.<br><br>I attached the output of 'configure', 'make', 'make install', and 'make testing'.<br>
<br>Best regards.<br>
