over tcp.<o:p></o:p></span></p>

<p class=MsoNormal>Dear Lustre users,<br>
I am using lustre
file system(<span class=gi>lustre-1.8.1</span>) over ib.Now i required
lustre over ib and over Ethernet also.<br>
I modified the modprobe.conf on client , mds(mdt),oss(ost).<br>
I add below line in modprobe.conf.<br>
options lnet networks=o2ib(ib0),tcp1(eth1)<br>
I am able to mount lustre over ib on client but not
able to mount over Ethernet.<br>
I am getting following error on stdout .<br>
<br>
mount.lustre: mount 172.29.2.25@tcp1:/home at /mnt
failed: No such file or directory<br>
Is the MGS specification correct?<br>
Is the file system name correct?<br>
If upgrading, is the copied client log valid? (see upgrade
docs)<br>
<br>
and /var/log/message is<br>
<br>
