For #3 you should look at "nodemap" and "subdirectory mount" in the
manual. I agree that simple user permissions should be the starting
point, but if you need more complete isolation (eg. if users are in charge of
VM images), then the following presentation will be useful:

Dear All,
During mdt it ask for --fsname flag , docs mentioned it is a name for filesystem name to which mdt part of .. that is ok but on client when i mount /lustre/fsname it mount complete lustre filesystem .

1) Can a mds/mdt serve more than one fsname ?

2) What is the best practice for maintaining different projects/users ? including home folders

3) Beside just linux uids, gids is there any better way of Authn/Authz in lustre ? for e..g I want a User X to mount only /lustre/fsname/homeX and /lustre/fsname/projectX folders .. no way he should mount /lustre/fsname.

any advice ?
