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.
