No, no, no...
This was my first idea, but then I understood that the root directory is
always on MDT0, so I had to migrate it to another server (after having
created two more, and crashed during migration).
I will later try to migrate to another server, and then delete MDT2.
But first I need to finish this lfsck... :-(
These "NOT IMPLEMETED (sic)" messages are just from running lfsck_start -A
