.Sh NAME
.Nm zpool-add
.Nd add vdevs to ZFS storage pool
.Sh SYNOPSIS
.Nm zpool
.Cm add
.Op Fl fgLnP
.Oo Fl o Ar property Ns = Ns Ar value Oc
.Ar pool vdev Ns …
.
.Sh DESCRIPTION
Adds the specified virtual devices to the given pool.
The
.Ar vdev
specification is described in the
.Em Virtual Devices
section of
.Xr zpoolconcepts 7 .
The behavior of the
.Fl f
option, and the device checks performed are described in the
.Nm zpool Cm create
subcommand.
.Bl -tag -width Ds
.It Fl f
Forces use of
.Ar vdev Ns s ,
even if they appear in use or specify a conflicting replication level.
Not all devices can be overridden in this manner.
.It Fl g
Display
.Ar vdev ,
GUIDs instead of the normal device names.
These GUIDs can be used in place of
device names for the zpool detach/offline/remove/replace commands.
.It Fl L
Display real paths for
.Ar vdev Ns s
resolving all symbolic links.
This can be used to look up the current block
device name regardless of the
.Pa /dev/disk
path used to open it.
.It Fl n
Displays the configuration that would be used without actually adding the
.Ar vdev Ns s .
The actual pool creation can still fail due to insufficient privileges or
device sharing.
.It Fl P
Display real paths for
.Ar vdev Ns s
instead of only the last component of the path.
This can be used in conjunction with the
.Fl L
flag.
.It Fl o Ar property Ns = Ns Ar value
Sets the given pool properties.
See the
.Xr zpoolprops 7
manual page for a list of valid properties that can be set.
The only property supported at the moment is
.Sy ashift .
.El
