From 8f2eba00fd315b42aeaa01d683b765fbd2ee111b Mon Sep 17 00:00:00 2001 From: shishir gowda Date: Tue, 24 Apr 2012 10:27:18 +0530 Subject: rebalance: handshake_event_notify to make fsd talk to glusterd Event_notify can be used by others to communicate with glusterd. A cbk event is also added for future use. req has a op, and dict. rsp has op_ret, op_errno, and dict. With this, rebalance process can update the status before exiting.
