# DESCRIPTION:
#    Check that `zpool labelclear` can clear labels on removed devices.
#
# STRATEGY:
# 1. Create a pool with primary, log, spare and cache devices.
# 2. Remove a top-level vdev, log, spare, and cache device.
# 3. Run `zpool labelclear` on the removed device.
# 4. Verify the label has been removed.
