From 84d88fd885de05a5f126a1f3661687c541001e39 Mon Sep 17 00:00:00 2001 From: Mariusz Tkaczyk Date: Wed, 1 Aug 2018 15:29:31 +0200 Subject: [PATCH] Grow: Frozen array can't be idle When array is frozen but there is no recovery/reshape in mdstat, check_idle() will not return error but grow countinue can still working. Check is array frozen. Do not use sysfs sync_action parameter because it doesn't exist for Raid0, simply check metadata_version in mdstat.
