Subject: [PATCH 086/115] dev_manager: accept misalined vdo pools.
|
||
|
|
|
||
|
|
Since lvm2 may create VDO pool virtual size aligned only on extent size
|
||
|
|
while VDO itself is just 4K aligned - we need to support such misalign.
|
||
|
|
|
||
|
|
(cherry picked from commit 2e79b005c2013fb03d8a48a3cfd8e70a982dd65b)
