Check
http://manual.lustre.org
When you mount the mds/mgs with -t lustre it activates the server.
You will also need 1 or more OSS (mkfs.lustre --ost )
You will then need to also mount it
Then on the client you mount like nfs
mount -t lustre mgshost:/lustre /test_share/
All the lustre information is built on top of ext3+patches, but you
can not access it directly (unless you mount without -t lustre which
mounts it ext3)
This is all spelled out in the manual.

Hi there,
I have just started a new position with a company that has a nice
20 node cluster.
This cluster is a nice setup, except they have not got any shared
storage setup, they did have NFS configured but the read times they
were getting for processing data was slowing the cluster down
considerably.
After looking around I have found lustre and thought I would
configure it on a spare node and see what kind of results I can get
from it.
So I have a system running Redhat Enterprise V 4 and have
downloaded the the pre built RPM’s from the following area on
clusterfs.com
http://www.clusterfs.com/downloads/public/Lustre/v1.6/Production/
latest/rhel-2.6-i686/
I’ve installed the new kernel and modified the grub.conf file so it
is being booted up.
Also I have installed
Kernel-lustre-source
Lustre-1.6.3-…
Lustre-debuginfo
Lustre-ldiskfs
Lustre-modules
Lustre source
Now at the moment I have a second 70Gb sata drive on the system I
would like to use as the lustre drive, so following the
instructions I have used the following command
Mkfs.lustre –mdt –mgs /dev/sdb
Which shows up all the right messages and is successful,
I then mount the drive
Mount –t lustre /dev/sdb /test_share
which successfully mounts and I can look at “cat /proc/fs/lustre/
devices” and can see all the right information.
Now the thing is if I try and write to this filesystem I get an error
Not a directory ????
So I’m kinda lost. What am I doing wrong ???????
If I mount the filesystem with a standard command
Mount /dev/sdb /test_share
I can see the following files and directories listed
[EMAIL PROTECTED] /]# ls /test_share
CONFIGS last_rcvd lost+found OBJECTS ROOT
health_check LOGS lov_objid PENDING
Help.
