| # DESCRIPTION: |
| # Verify that 'zfs set sharenfs=on', 'zfs share', and 'zfs unshare' can |
| # run concurrently. The test creates 50 filesystem and 50 threads. |
| # Each thread will run through the test strategy in parallel. |
| # |
| # STRATEGY: |
| # 1. Verify that the file system is not shared. |
| # 2. Enable the 'sharenfs' property |
| # 3. Invoke 'zfs unshare' and verify filesystem is no longer shared |
| # 4. Invoke 'zfs share'. |
| # 4. Verify that the file system is shared. |
| # 5. Verify that a shared filesystem cannot be shared again. |
| # 6. Verify that share -a succeeds. |
