pool device new_device- Attaches new_device to the existing
device. The existing device cannot be
part of a raidz configuration. If device
is not currently part of a mirrored configuration,
device automatically transforms into a
two-way mirror of device and
new_device. If
device is part of a two-way mirror,
attaching new_device creates a three-way
mirror, and so on. In either case,
new_device begins to resilver immediately
and any running scrub is cancelled.
-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(8) 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 verfied during sequential reconstruction so a scrub is started
when the resilver completes. Sequential reconstruction is not
supported for raidz configurations.
-w- Waits until new_device has finished
resilvering before returning.
