No, because it's a filesystem label for the ext4 fs created on /dev/sdz1. If sdz1 is turned into an LVM Physical Volume, there won't be an ext4 filesystem on it any more. If sdz1 is turned into a member of an MD array, there won't be an ext4 filesystem on it any more. The labels go with the filesystem. > and can be unique?

Once the RAID and/or LVM is set up and a filesystem put on it, that filesystem can be mounted by label just like any filesystem can, but that filesystem may have multiple devices underneath it owing to the fact that it's on RAID and/or LVM, so there is no information you can put in its label that will tell you anything about those underlying devices. > if all 3 questions above can be answered with a yes is the answer > I've been trying to squeeze out all along. You've not yet been clear about what you want, but from what little information you have provided you've been told multiple times by multiple people that filesystem labels won't help.
