More comments here, Should we keep the default behavior like before? e.g. VG/LV should be auto-activated by default like before.Otherwise, some users will feel strange after lvm upgrade. Second, how to keep the compatibility with the existed VG/LV? since we can upgrade lvm2 version, but VG/LV is possible old. I wonder if there are some Reserved Bits in lvm meta-data layout to use? if yes, I feel this proposal is very perfect.
