- # DESCRIPTION:
- # When set property devices=off on file system, device files cannot be used
- # in this file system.
- #
- # STRATEGY:
- # 1. Create pool and file system.
- # 2. Set devices=off on this file system.
- # 3. Separately create block device file and character file.
- # 4. Separately read and write from those two device files.
- # 5. Check the return value, and make sure it failed.

- log_onexit cleanup
- log_must zfs set devices=off $TESTPOOL/$TESTFS
- #
- # Create block device file backed by a ZFS volume.
- # Verify it cannot be opened, written, and read.
