When brick multiplexing enabled, upon snapshot restore, glusterd was sending the volume file of a client to the snapshot brick instead of sending the brick volume file. So, the multiplexed snapshot brick process starts to use that volume file.


This results in some of the snapshot bricks to become clients resulting in unavailability of the snapshot data to the applications. In short, the brick process gets converted into a client process.


Fix has been made to glusterd to send proper volume file to the snapshot brick process when brick multiplexing is enabled. 


Now, glusterd sends the proper volume file to the multiplexed snapshot brick process when a snapshot restore is done.
