Hi Gupta,
What I see is
1. there is no MDS and/or filesystem name
2. mount command did not specify filesystem name, otherwise the
filesystem name is "client1"
try preparing MDT volume and format it with a filesystem name( on the MGS
is okay) and mount the MDT, and retry lustre mount with following command
[root at Client ~]# mount -t lustre 10.177.33.10 at tcp:/<FILESYSTEMNAME>
/mnt/lustre
Regards,
Jongwoo Han
