That is starting to make sense.. Let me summarize so I have got it right Current mkfs.lustre --fsname=temp --mgs --mdt --index=0 /dev/mapper/mpathcp1 - On MDS/MGS mkfs.lustre --ost --fsname=client1 --reformat --index=0 --mgsnode=10.177.33.10@tcp0 /dev/zvol/LSD1Pool/LusterVola0 - ON OST New mkf

Amit, Are you by any chance specifying a unique value for --fsname for each of the MDT/OSTs? If so, keep in mind that fsname needs to be the same when you format all the MDT/OST devices and that the fsname doesn't have anything to do with the mount point for the MDT/OSTs. --Rick On Jan 8,

Re: [Lustre-discuss] [EXTERNAL] Re: Newbie - Unable to mount the OST on the Client

In lustre you MUST have a MGS _AND_ MDS node and an associated MDT (file system) running on the MDS. Typically the MDS and MGS are configured on the same node. If you don't have this, lustre won't work. Joe Mervini Sandia National Laboratories High Performance Computing 505.844.6770 jame..

Re: [Lustre-discuss] Newbie - Unable to mount the OST on the Client

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 /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 fil
