So the only LV name "mds" there is properly activated.

LVM will not activate partitions on the LV automatically,
but you can use "kpartx" utility to do that (see man kpartx).

Try "kpartx -a /dev/mds/mds"

(before deactivating LV you will need run kpartx -d to remove these
partition mappings again.)
