When an OST dies and you have no choice but replacing it with a newly freshly 
formatted one (using mkfs --replace), Lustre runs a resynchronization 
mechanisms between the MDT and the OST.
The MDT will sent the last object ID it knows for this OST and the OST will 
compare this value with its own counter (0 for a freshly formatted OST).
If the difference is greater than 100,000 objects, it will recreate only the 
last 10,000, if not, it will recreate all the missing objects.

I would like it to avoid recreating any objects. The missing ones are lost and 
just start recreating new ones. Is there a way to achieve that?
