From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mariusz Tkaczyk Subject: [PATCH] Detail: differentiate between container and inactive arrays Date: Fri, 18 Aug 2017 12:00:23 +0200 Message-ID: <1503050423-20984-1-git-send-email-mariusz.tkaczyk@intel.com> Return-path: Sender: linux-raid-owner@vger.kernel.org To: jes.sorensen@gmail.com Cc: linux-raid@vger.kernel.org, Mariusz Tkaczyk List-Id: linux-raid.ids Containers used to be handled as active arrays because GET_ARRAY_INFO ioctl returns valid structure for them. As containers appear as inactive in sysfs, the output for detail command has changed. Stop relying on inactive state for containers. Make the output look the same as in mdadm 4.0.
