[Lustre-discuss] cannot mount client to work

[Tanin]

*I try to install the MDT, OSS and client on the same server with Red hat
Enterprise 5.3. And I tried to install all the RPMs required:

*Then, I kept going according to the "Lustre file system: demo quick start
guide", every thing went fine. I can mount both MDT and OSTs, till I came to
mount the client with:*
*[root at localhost Desktop]# mount -t lustre 192.168.5.131 at tcp0:/lustre
/mnt/lustre
mount.lustre: mount 192.168.5.131 at tcp0:/lustre at /mnt/lustre failed:
Invalid argument
This may have multiple causes.
Is 'lustre' the correct filesystem name?
Are the mount options correct?
Check the syslog for more info.*
*
So, I check the syslog it shows the message of:*

*Oct 13 17:44:38 localhost kernel: LustreError: 156-2: The client profile
'lustre-client' could not be read from the MGS.  Does that filesystem exist?
Oct 13 17:44:38 localhost kernel: LustreError:
6046:0:(obd_mount.c:2045:lustre_fill_super()) Unable to mount  (-22)*


I have check the former question of the list, none of the solution works. Do
you guys have any suggestion? Thanks a lot!
