| |
| # |
| # DESCRIPTION: |
| # Once zpool set autoexpand=on poolname, zpool can 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=on |
| # 3) Expand each device as appropriate |
| # 4) Check that the pool size was 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. |
| # |
| |
| verify_runnable "global" |
| |
| # We override $org_size and $exp_size from zpool_expand.cfg to make sure we get |
| # an expected free space value every time. Otherwise, if we left it |
| # configurable, the free space ratio to pool size ratio would diverge too much |
| # much at low $org_size values. |
| # |
| org_size=$((1024 * 1024 * 1024)) |
