| # DESCRIPTION: |
| # With 'compression' or 'compress' set, changing filesystem blocksize cannot |
| # cause system panic |
| # |
| # STRATEGY: |
| # 1. Set 'compression' or "compress" to on |
| # 2. Set different blocksize with ZFS filesystem |
| # 3. Use 'mkfile' create single block and multi-block files |
| # 4. Verify the system continued work |
| # |
