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.)

.Dt ZPOOL-REPLACE 8

|
.Os
|
|
.Sh NAME
|
|
.Nm zpool-replace
|
|
.Nd Replace one device with another in a ZFS storage pool
|
|
.Sh SYNOPSIS
|
|
.Nm zpool
|
|
.Cm replace
|
|

|
|
.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 zpool
|
|
.Cm replace
|
|
.Op Fl fsw
|
|
.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 .
|
|
Any in progress scrub will be cancelled.
|
|
.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 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 the replacement has completed before returning.
