[Lustre-discuss] Issue regarding lustre client mountpoint

[linux freaker]

Hi Lee,

I have one lustreclient1 working fine. I followed it this way:

# lustre_rmmod

#modprobe lustre
#mount -t lustre 192.168.1.1 at o2ib0:/lustre /mnt/lustre

and it worked fine.

But when I am trying the same stuff on another machine, it threw the error:

 but another having some issue.

# lustre_rmmod
Modules still loaded:
lnet/klnds/socklnd/ksocklnd.o lnet/lnet/lnet.o libcfs/libcfs/libcfs.o

# modprobe lustre

such file or directory
Is the MGS specification correct?
Is the filesystem name correct?
If upgrading, is the copied client log valid? (see upgrade docs)
