	The recommended practice for `.Os` on FreeBSD is to not specify any arguments. The correct OS name is used automatically. Oddly enough, on the Linux distro I tested this on (CentOS 7), the man pager defaulted to displaying "BSD" as the OS rather than "Linux". To accommodate this, tack " Linux" back on in an install hook on Linux. This is much simpler than removing it for FreeBSD when vendored in the base system.

.Nd Attach a new device to an existing ZFS virtual device (vdev).

						|
.Oo Fl o Ar property Ns = Ns Ar value Oc
 | 
						|
.Ar pool device new_device
 | 
						|
.Xc
 | 
						|
Attaches
 | 
						|
.Ar new_device
 | 
						|
to the existing
 | 
						|
.Ar device .
 | 
						|
The existing device cannot be part of a raidz configuration.
 | 
						|
If
 | 
						|
.Ar device
 | 
						|
is not currently part of a mirrored configuration,
 | 
						|
.Ar device
 | 
						|
automatically transforms into a two-way mirror of
 | 
						|
.Ar device
 | 
						|
and
 | 
						|
.Ar new_device .
 | 
						|
If
 | 
						|
.Ar device
 | 
						|
is part of a two-way mirror, attaching
 | 
						|
.Ar new_device
 | 
						|
creates a three-way mirror, and so on.
 | 
						|
In either case,
 | 
						|
.Ar new_device
 | 
						|
begins to resilver immediately and any running scrub is cancelled.
 | 
						|
.Bl -tag -width Ds
 | 
						|
.It Fl f
 | 
						|
Forces use of
 | 
						|
.Ar new_device ,
 | 
						|
even if it appears to be in use.
 | 
						|
Not all devices can be overridden in this manner.
 | 
						|
.It Fl o Ar property Ns = Ns Ar value
 | 
						|
Sets the given pool properties. See the
 | 
						|
.Xr zpoolprops 8
 | 
						|
manual page for a list of valid properties that can be set. The only property
 | 
						|
supported at the moment is ashift.
 | 
						|
.It Fl s
 | 
						|
The
 | 
						|
.Ar 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.
 | 
						|
.It Fl w
 | 
						|
Waits until
 | 
						|
.Ar new_device
 | 
						|
has finished resilvering before returning.
