[lustre-discuss] OST -> MDT migration and MDT -> OST migration

   Hi All,

   I'm trying to figure out how to migrate files stored on an OST to an MDT
(that's using DoM) and to migrate files stored on an MDT to an OST (e.g.,
if the MDT is getting full).  I can see how to migrate between OSTs, but
not between OSTs and MDTs.  I'm running Lustre 2.12.3.

   Do you happen to know the syntax for migration between OSTs and MDTs?

   Thanks for any help!

   Bill
