Bug Description

Thin-provisioned LVs may not be activated automatically in all cases. (RHEL 6.5 does not activate them automatically by default.)

This causes the volume clone from snapshot dd operation to fail, as the source device does not exist in /dev/mapper/. We should ensure the LV is active before attempting to clone to a new volume.

    LVM: Activate source LV before cloning from it

    LVM may be configured to not automatically activate
    thin-provisioned LVs.

    Ensure they are activated when performing a clone, otherwise
    dd will fail as the device does not exist in /dev/mapper/.

    LVM: Activate source snap LV when cloning from volume

    Similar to the change made in:
    01a2199 LVM: Activate source LV before cloning from it

    Previous change only fixed this issue for clone-from-snapshot.

    This activates the source snapshot LV when cloning from volume
    as well, fixing the problem where cloning fails due to inability
    to open the source LV device.
