Dear list, I got some basic questions concerning how file access in Lustre works: from what I understand, Lustre clients lock file ranges with the server before executing I/O operations. What does a client get on its next I/O call in case the server needs to revoke the lock (the server can do that, right?): does the client try to re-acquire the lock, block and then time out (in case the server does not grant the lock again to that client)?
TIA, Arne
