I ma installing MPICH-1.2.6 ch_p4 version on my Opteron cluster running
AMD64, the test case failed with message:
< p2_17986: p4_error: : 1
< File locking failed in ADIOI_Set_lock. If the file system is NFS, you
need to use NFS version 3, ensure that the lockd daemon is running on
all the machines, and mount the directory with the 'noac' option (no
<  MPI Abort by user Aborting program !
<  Aborting program!
I checked my file system:
Zephyr:~ # rpcinfo -p `hostname `| grep nfs
100003 2 udp 2049 nfs
100003 2 tcp 2049 nfs
and found that the installed NFS is version2,
How to convert it to version 3? do I need to upgrade related NFS
modules? any hint is appreciated.
