Inactive VG should not have any /dev/ content. If it remained after
deactivation, it seems to be a bug in node/symlink handling under /dev.

A few questions then:

  - what distro is this?
  - are you using udev rules from lvm2 git repo too?
  - what are the lvm.conf values for these settings:
      - activation/udev_sync
      - activation/udev_rules
      - activation/verify_udev_operations
  - what udev (or systemd+udev) version is being used
  - are all the items found in /dev/mapper symlinks (not direct block dev nodes)?
  - are there dangling symlinks found in /dev/mapper for the LVs from deactivated VG?
