Hi,
<div><br></div><div>I'm using CentOS 5.4 with OFED-1.5-rc3 and Mellanox ConnectX cards.</div><div>I follow the steps of nfs-rdma.release-notes.txt and can use NFS over RDMA successfully in the first time.</div><div>However, after umount the file system and restart the NFS server, it shows the following error:</div>
<div><br></div><div><div># /etc/init.d/nfs stop</div><div>Shutting down NFS mountd: [ OK ]</div><div>Shutting down NFS daemon: [ OK ]</div><div>Shutting down NFS quotas: [ OK ]</div>

<div><br></div></div><div>And in the client side, I can no longer mount the server again.</div><div><br></div><div>Is there a correct ways to restart the NFS server after configuring NFSoRDMA?</div><div><br></div><div>Thanks in advance.</div>
