As I understand it it depends on how you've got the one system mounted. If you're mounting through Gluster, the theory of it is that any creation/modification goes to both systems at once, so the situation you're worried about could happen, but only if the file creation/modification was in the middle of happening and had not completed on one system at the time the system it hadn't completed on went down. That would be when triggering the "healing" is required to sync them later. So the way you've put the question, about halting the first system, no that shouldn't block the replication - unless you'd also mounted the first system _outside_ of Gluster, and wrote/modified the file on it directly. That's where the confusion came in that started this thread. At least that's what I make of it. Whit
