Subject: [PATCH 109/115] lvm_import_vdo: correct the converted virtual size
|
|
|
|
Ensure the volume after conversion has the properly aligned size to the
|
|
volume group extent size. This would be visible when using virtual size,
|
|
that cannot be divided by extent size.
|
|
|
|
Before the user had to manually adjust the size after conversion to get
|
|
access to all data stored on VDO volume.
|
|
|
|
(cherry picked from commit 657dde6208ddc8172b7d0e1466751046c8ddaeaa)
