| # |
| # Description: |
| # Once set zpool autoexpand=off, zpool can *NOT* autoexpand by |
| # Dynamic VDEV Expansion |
| # |
| # |
| # STRATEGY: |
| # 1) Create three vdevs (loopback, scsi_debug, and file) |
| # 2) Create pool by using the different devices and set autoexpand=off |
| # 3) Expand each device as appropriate |
| # 4) Check that the pool size is not expanded |
| # |
| # NOTE: Three different device types are used in this test to verify |
| # expansion of non-partitioned block devices (loopback), partitioned |
| # block devices (scsi_debug), and non-disk file vdevs. ZFS volumes |
| # are not used in order to avoid a possible lock inversion when |
| # layering pools on zvols. |
