From ff3c881f84f63d805cfd9bc05772a33a25c8bd6f Mon Sep 17 00:00:00 2001 From: Song Liu Date: Thu, 11 Aug 2016 17:10:04 -0700 Subject: [PATCH] mdadm: add man page for --add-journal Add the following to man page: --add-journal Recreate journal for RAID-4/5/6 array that lost a journal device. In the current implementation, this command cannot add a journal to an array that had a failed journal. To avoid interrupting on-going write opertion --add-journal only works for array in Read-Only state.
