attach new device to existing ZFS vdev
zpool |
attach [-fsw ]
[-o
property=value]
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 verified
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.
