Subject: [PATCH lvconvert 5/11] Don't insert temporary layer for corelog mirror
Date: Fri, 04 Jan 2008 10:12:31 -0500 [thread overview]
Message-ID: <477E4CDF.8060501@ce.jp.nec.com> (raw)
In-Reply-To: <477E48D8.4050404@ce.jp.nec.com>
lvconvert inserts a temporary layer so that it can sync newly added
mirrors while keeping the original mirror in-sync.
However, LVM2 manages in-sync status for corelog mirror by
the global _mirror_in_sync variable.
So the insertion just duplicates the sync effort.
If the original mirror is corelog, we can just add mimage LV to it
and restart sync.
Thanks,
