Hi,

Given that an MD RAID array or a LVM Logical Volume may be spread
across many different underlying storage devices, the question
doesn't make sense. Due to the fact that filesystems go on block
devices, and RAID arrays and LVM LVs can be block devices, a
filesystem label in that instance would represent possibly multiple
underlying storage devices. So step back and tell us what are you
actually trying to achieve, rather than insisting on your X solution
to your Y problem.

Suppose you have the MD array /dev/md42. What are you conceptually
wanting to do with that in relation to labels of some kind? What
information is it that you want?

Support you have LVM logical volume /dev/myvg/mylv. What are you
conceptually wanting to do with that in relation to labels of some
kind? What information is it that you want?

Once you explain what information you're trying to get when you
start with an LVM or MD device, I can probably advise how to get it,
but just to make clear: I don't think it's a good idea to continue
to use such broken devices. We don't need to debate that since I
know you've been posting about that a lot and clearly have decided
to push ahead. I just think you haven't seen the end of the problems
with that issue.

Regards,
Andy
