zpool-replace
—
replace one device with another in ZFS storage pool
zpool |
replace [-fsw ]
[-o
property=value]
pool device
[new-device] |
Replaces device with new-device.
This is equivalent to attaching new-device, waiting for
it to resilver, and then detaching 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
configuration.
new-device is required if the pool is not
redundant. If new-device is not specified, it defaults
to 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.
-f
- Forces use of new-device, even if it appears to be
in use. Not all devices can be overridden in this manner.
-o
property=value
- Sets the given pool properties. See the
zpoolprops(7)
manual page for a list of valid properties that can be set. The only
property supported at the moment is ashift.
-s
- The new-device is reconstructed sequentially to
restore redundancy as quickly as possible. Checksums are not verified
during sequential reconstruction so a scrub is started when the resilver
completes. Sequential reconstruction is not supported for raidz
configurations.
-w
- Waits until the replacement has completed before returning.
