From e873fdb5259ac62cf099621590645470c12a1d21 Mon Sep 17 00:00:00 2001 From: Noboru Iwamatsu Date: Wed, 3 Jul 2013 15:01:04 -0700 Subject: [PATCH] ocfs2: submit disk heartbeat bio using WRITE_SYNC Under heavy I/O load, writing the disk heartbeat can be forced to wait for minutes, and this causes the node to be fenced. This patch tries to use WRITE_SYNC in submitting the heartbeat bio, so that writing the heartbeat will have a priority over other requests.
