Replace one device with another in a ZFS storage
-oproperty=value] pool device [new_device]
- 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
The size of new_device must be greater than or equal to the minimum size of all the devices in a mirror or raidz configuration.
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.
