From bd18f6462f3d167a9b3ec27851c98f82694b2adf Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Wed, 2 Sep 2015 13:49:50 -0700 Subject: md: skip resync for raid array with journal If a raid array has journal, the journal can guarantee the consistency, we can skip resync after a unclean shutdown. The exception is raid creation or user initiated resync, which we still do a raid resync.
