+# DESCRIPTION:
+# 'zfs remap' depends on 'feature@obsolete_counts' being active
+#
+# STRATEGY:
+# 1. Prepare a pool where a top-level VDEV has been removed and with
+#    feature@obsolete_counts disabled
+# 2. Verify any 'zfs remap' command cannot be executed
+# 3. Verify the same commands complete successfully when
+#    feature@obsolete_counts is enabled
+#
