Hi,

Sorry if these questions duplicates previous debate.

Have I understood correctly that the design allows individual objects
within a lustre file (i.e. stripes?) to be purged independently?

If so why is this needed?

I would have thought that when you purge a file, you need only record
the purged extent as an attribute of the whole lustre file and punch
its stripes to free the space.  Am I missing a use case?
