+# DESCRIPTION:
+# check 'zfs create <filesystem>' works at the name length boundary
+#
+# STRATEGY:
+# 1. Verify creating filesystem with name length 255 would succeed
+# 2. Verify creating filesystem with name length 256 would fail
+# 3. Verify the pool can be re-imported
+
+verify_runnable "both"
+
+# namelen 255 and 256
