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@Client ~]# mount -t lustre 10.177.33.10@tcp:/<FILESYSTEMNAME> /mnt/lustre Regards, Jongwoo Han 2015-01-07 22:25 GMT+09:00 Gupta, Amit <[email protected]>: > Hi All , > > > > Need some guidance on getting past this error that I get mounting the OST > on the Client.
