Dear Sam,
<div> </div>
<div>My purpose is to let client very easy to connect to server, no any extra installation needed in client site. That's why I put NFS on the top of the system.</div>
<div> </div>
<div>The good news is if I changed to 32 bit (version 2.8.2), it works. No such error.</div>
<div>Is there anyone can give me help to let me understand why 64 bit doesn't work?</div>
<div> </div>
<div>Thanks in advance,</div>
<div> </div>
<div>Bob</div>

<div><br></div>Hi Bob,
<div><br></div>
<div>I'm not sure yet why you get that error, but I have a question about your setup. Why not just mount PVFS on the client machine, instead of trying to use NFS? That may work around the problem you're seeing.</div>

<div>Here is the NFS/PVFS setup:</div>
<div>1) PVFS setup:<br> 1 meta server and 1 io server<br> both have pvfs2 installed and started without error<br> pvfs2-ping -m /mnt/pvfs2 shows no error.</div>
<div> on meta server:<br> run the following:<br> a) /sbin/insmod /usr/local/bin/pvfs2/pvfs2.ko<br> b) /usr/local/bin/pvfs2/sbin/pvfs2-client -p /usr/local/bin/pvfs2/sbin/pvfs2-client-core<br> c) mount -t pvfs2 <a>tcp://meta_server:3334/pvfs2-fs</a> /mnt/pvfs2</div>
<div> 2) NFS setup on meta_server:<br> a) Created /etc/exports file:<br> /mnt/pvfs2 *(sw,sync,fsid=0,insecure,no_subtree_check)<br> b) run:<br> exportfs -rav<br> rpc.mountd<br>
rpc.nfsd 8</div>
<div> c) On a NFS client machine:<br> run:<br> showmount -e meta-server<br> it display /mnt/pvfs2 exported to everyone<br> <br> mkdir /testmnt<br> mount meta_server:/mnt/pvfs2 /testmnt<br>
<br> mount was successful without error<br> df -h sees NFS mounted directory /testmnt on meta_server<br> cd /testmnt successful without error<br> mkdir test successful without error<br>
cd test shows the error:</div>

<div>Bob, can you give us some more details about your NFS/PVFS setup? Which directory are you NFS mounting? Usually PVFS and NFS mounts are separate.<br><br>-sam<br><br>><br></div>
<div>> This error is for the version 2.8.1. The same error displayed for version 2.8.2.<br>><br>> Can anyone help me? Thanks in advance.<br>><br>> Bob<br></div>
