There is only 1 filesystem per MDT. So you can either organize your

--mgsnode=<mgsnodenid> on the others.
Thank Nathaniel,
From your reply I understand that Lustre can has 1 MDT per node right ?
If I want to have 3 file system as I mention before I must setup
1 node for MGS/ 1MDT and 2 nodes for 2 MDTs (1 MDT on each node) .
Please correct me If I wrong.
Well, those are sufficient but not necessary conditions. If you
substitute "disk" for
"node" you would be more accurate. And you could set up 1 disk for a
standalone
MGS and 3 disks for 3 MDTs if you wanted. The MGS disk can be small; it
just
needs to hold configuration data.
