Use proper names (i.e. zfs-allow and zpool-add) in NAME subsections of zfs/zpool subcommands instead of current "pretty-printed" ones as makewhatis utilities (or some implementations of it, namely the one from mandoc suite used in FreeBSD) look not only at the document title but also in NAME subsection, adding zfs(8)/zpool(8) to search results which is not correct. (Common sense and other utilities splitting subcommands in multiple man pages, e.g. git, do the same.)

.Nm zpool-attach
|

.Op Fl fsw

.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.
