Sure.  In fact, if you have access to the red hat 5.3 beta, it is
ready there.

       Hello,


       will the changes to mirroring get merged into stable2 and
       head after
       RHEL-5.3 release?

that works already.

single machine: linear, stripe, mirror, snapshot
cluster-aware: linear, stripe, mirror (5.3)

What about CLVM based striping (RAID0)? Does that work
       already or is
it planned for the near future?

wouldn't count
on it supporting anything more advanced.

I worked a little on clvm snapshots:

Review and testing is required.
