mirror_zfs/man/man8/zpool-replace.8
Ross Williams c5ebfbbe19 Reorganize zpool(8) man page into sections
Moved subcommand topics into individual manpages. Reordered and 
grouped the list of subcommands by topic.

Moved concepts overview to `zpoolconcepts.8` and the long list of
available pool properties to `zpoolprops.8`.

Internal cross-references copied from `zpool.8` needed to be 
converted to `.Xr` external references to new subcommand manual 
pages.

Move `autotrim` into lexical order, autotrim tacked onto the end
of a list. Now it is in alphabetical order.

Clarify attach/detach description. Description was too specific to
command syntax. Overview clarifies reason for attaching or detaching
a device.

Clarify replace description, don't refer to subcommand arguments.

Clarify split command description, say what split actually does and
why you'd want to do it.

Clarify description of upgrade, and simplify the zpool.8 wording of
the zpool-upgrade(8) description.

Clarify description of import, detail what zpool-import(8) actually 
does.

Add appropriate SEE ALSO sections. Divided zpool subcommand manual 
pages need their own SEE ALSO sections. Also modified fsck.zfs.8 
to point directly to zfs-scrub.8 and zed.8.in to include a direct
reference to zfs-events.8

.Dt ZPOOL-REPLACE 8
.Os Linux
.Sh NAME
.Nm zpool Ns Pf - Cm replace
.Nd Replace one device with another in a ZFS storage pool
.Sh SYNOPSIS
.Nm
.Cm replace
.Op Fl fw
.Oo Fl o Ar property Ns = Ns Ar value Oc
.Ar pool Ar device Op Ar new_device
.Sh DESCRIPTION
.Bl -tag -width Ds
.It Xo
.Nm
.Cm replace
.Op Fl fw
.Op Fl o Ar property Ns = Ns Ar value
.Ar pool Ar device Op Ar new_device
.Xc
Replaces
.Ar old_device
with
.Ar new_device .
This is equivalent to attaching
.Ar new_device ,
waiting for it to resilver, and then detaching
.Ar old_device .
.Pp
The size of
.Ar new_device
must be greater than or equal to the minimum size of all the devices in a mirror
or raidz configuration.
.Pp
.Ar new_device
is required if the pool is not redundant.
If
.Ar new_device
is not specified, it defaults to
.Ar old_device .
This form of replacement is useful after an existing disk has failed and has
been physically replaced.
In this case, the new disk may have the same
.Pa /dev
path as the old device, even though it is actually a different disk.
ZFS recognizes this.
.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
manual page for a list of valid properties that can be set.
The only property supported at the moment is
.Sy ashift .
.It Fl w
Waits until the replacement has completed before returning.
