  31 # DESCRIPTION:
  32 # Verify that 'zfs set sharenfs' and 'zfs share' shares a given dataset.
  33 #
  34 # STRATEGY:
  35 # 1. Invoke 'zfs set sharenfs'.
  36 # 2. Verify that the file system is shared.
  37 # 3. Invoke 'zfs share'.
  38 # 4. Verify that the file system is shared.
  39 # 5. Verify that a shared filesystem cannot be shared again.
  40 # 6. Verify that share -a succeeds.
