Hi List,<br>
<br>
I'm running WRF on a large cluster with a Lustre file system
(redmesa.sandia.gov) and am encountering the following error on one
of the processes doing a write through pNetCDF over OpenMPI:<br>
<br>
<blockquote><font color="#000099">File locking failed in
ADIOI_Set_lock(fd 18,cmd F_SETLKW/7,type F_WRLCK/1,whence 0)
with return value FFFFFFFF and errno 26.<br>
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 attribute caching).<br>
ADIOI_Set_lock:: Function not implemented<br>
ADIOI_Set_lock:offset 74588, length 804</font><br>
</blockquote>
<br>
Have Googled this a little before writing to this list, and the
workaround seems to be to upgrade to NFS v3, but that's outside my
purview and I don't know if that's applicable to this Lustre system
anyway. Have you seen this before? Any thoughts or suggestions?
Thanks,<br>
<br>
