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! You just use "lfs migrate <file layout> <file>" to migrate from DoM files to OST objects. However, OST-to-DoM migration isn't available until 2.13.
