Subject: [PATCH 09/12] imsm: Write empty PPL header if assembling regular clean array.
Date: Thu, 28 Sep 2017 14:41:15 +0200 [thread overview]
Message-ID: <20170928124118.23361-10-pawel.baldysiak@intel.com> (raw)
In-Reply-To: <20170928124118.23361-1-pawel.baldysiak@intel.com>
If array was initially assembled with kernel without PPL support -
initial header was never written to the drive.
If initial resync was completed and system is rebooted to kernel with
PPL support - mdadm prevents from assembling normal clean array
due to lack of valid PPL.
Write empty header when assemble normal clean array, so the
its assamble is no longer blocked.
