Subject: [PATCH 26/27] DDF: ddf_process_update: Fix vlist treatment for SVDs
Date: Wed, 3 Jul 2013 22:28:06 +0200 [thread overview]
Message-ID: <1372883287-8859-27-git-send-email-mwilck@arcor.de> (raw)
In-Reply-To: <1372883287-8859-1-git-send-email-mwilck@arcor.de>
With secondary RAID level, disks may belong to other BVDs in
a given conf record. This needs to be taken into account
when fixing the vlist.
