| # DESCRIPTION: |
| # Spare devices (both files and disks) can be shared among different ZFS pools. |
| # |
| # STRATEGY: |
| # 1. Create two pools |
| # 2. Add the same spare device to different pools |
| # 3. Inject IO errors with a zinject error handler |
| # 4. Start a scrub |
| # 5. Verify the ZED kicks in a hot spare and check pool/device status |
| # 6. Clear the fault |
| # 7. Verify the hot spare is available and check pool/device status |
