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(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 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.
