From df8c676418e1eb6f7bbafc1e01983f3538584894 Mon Sep 17 00:00:00 2001 From: Guoqing Jiang Date: Mon, 2 Jul 2018 16:26:26 +0800 Subject: [PATCH] md-cluster: don't send msg if array is closing If we close an array which resync thread is running, then we don't need the node to send msg since another node would launch the resync thread to continue the rest works. Also send a message is time consuming, we should avoid it.
