Client level Raid1 or Raid5 isn't possible; however CFS has been working on the infrastructure for adding such support to Lustre, from a Lustre cvs commit message:

Add new LOV EA format which gives us fields for features needed in the post

storage than the current layout when there are few stripes on lots of OSTs.
