At the moment, LVM RAID is only supported with conventional/thick

provisioning, you still need to use mdadm (or hardware RAID).
You can do thin pools as RAID[1,5,N], just not in a single command:
|root #||lvcreate -m 1 --type raid1 -l40%VG -n thin_pool vg0 |
|root #||lvcreate -m 1 --type raid1 -L4MB -n thin_meta vg0 |
|root #||lvconvert --thinpool vg0/thin_pool --poolmetadata vg00/thin_meta
So yeah, it's not directly supported by the tools but it does work. I
would not recommend it though as I doubt it is very well tested.
