Replace one device with another in a ZFS storage pool

- Replaces old_device with
new_device. This is equivalent to
attaching new_device, waiting for it to
resilver, and then detaching old_device.
Any in progress scrub will be cancelled.
The size of new_device must be greater than
or equal to the minimum size of all the devices in a mirror or raidz
new_device is required if the pool is not
redundant. If new_device is not
specified, it defaults to old_device.
This form of replacement is useful after an existing disk has failed and
has been physically replaced. In this case, the new disk may have the same
/dev path as the old device, even
though it is actually a different disk. ZFS recognizes this.
- Forces use of new_device, even if it appears to be in use. Not all devices can be overridden in this manner.
- Sets the given pool properties. See the zpoolprops manual page for a list of valid properties that can be set. The only property supported at the moment is ashift.
- The new_device is reconstructed sequentially to restore redundancy as quickly as possible. Checksums are not verfied during sequential reconstruction so a scrub is started when the resilver completes. Sequential reconstruction is not supported for raidz configurations.
- Waits until the replacement has completed before returning.
