Hi,
please don't create new threads for the same topic. So it seems that
'rhel' is the name of the VG you're trying to activate, correct?
To mount it you need to mount the path to the LV instead of the
partition as I already wrote in my earlier response [1].
Try again with:
mount /dev/rhel/root /mnt
