From 9aa574a51b84717c1f3949ed2e28a49e49840a93 Mon Sep 17 00:00:00 2001 From: Amar Tumballi Date: Sun, 22 Oct 2017 12:41:38 +0530 Subject: protocol/client: handle the subdir handshake properly for add-brick There should be different way we handle handshake in case of subdir mount for the first time, and in case of subsequent graph changes.
