vgoyal added a new comment to an issue you are following: ``
What I'm hearing is the "flip back to devicemapper without repartitioning" path doesn't actually exist.
Flipping back to devicemapper will require free space. And that would be possible only if ext4 and xfs had online shrink support. That way one could have shrunk rootfs and made space for devicemapper consumtion.
Xfs does not support shrinking and ext4 supports only offline shrinking. So this option does not work. ``
