[Lustre-discuss] How to remove OST permanently?

All,

I've added a new 2.2 TB OST to my cluster easily enough, but this new 
disk array is meant to replace several smaller OSTs that I used to have 
of which were only 120 GB, 500 GB, and 700 GB.

Adding an OST is easy, but how do I REMOVE the small OSTs that I no 
longer want to be part of my cluster?  Is there a command to tell luster 
to move all the file stripes off one of the nodes?
