Jongwoo, This is the mount command that is being used on the client machine [root@Client ~]# mount -t lustre 10.177.33.10@tcp:/client1<mailto:10.177.33.10@tcp:/client1> /mnt/lustre
Here 10.177.33.10 is the MGS Server and “client1” is the filesystem name for the OST On the OSS, here is this filesystem mounted as /dev/zd912 1069706420 483556 1013552180 1% /client1 The commands used on OST to mount and format “client1” were mkfs.lustre --ost --fsname=client1 --reformat --index=0 --mgsnode=10.177.33.10@tcp0 /dev/zvol/LSD1Pool/LusterVola0 mount -t lustre /dev/zvol/LSD1Pool/LusterVola0 /client1 From: 한종우 [mailto:jw....@apexcns.com] Sent: Wednesday, January 07, 2015 9:20 PM To: Gupta, Amit Cc: lustre-discuss@lists.lustre.org Subject: Re: [Lustre-discuss] Newbie - Unable to mount the OST on the Client 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<mailto:10.177.33.10@tcp:/%3cFILESYSTEMNAME>> /mnt/lustre Regards, Jongwoo Han 2015-01-07 22:25 GMT+09:00 Gupta, Amit <amit.gu...@optum.com<mailto:amit.gu...@optum.com>>: Hi All , Need some guidance on getting past this error that I get mounting the OST on the Client. This is the first time I am trying to mount it so not sure what I could be missing.. I will be glad to provide any other logs that would be helpful to determine the root cause of this issue..
