.Dt ZPOOL-REPLACE 8
|
|
.Os
|
|
.
|
|
.Sh NAME
|
|
.Nm zpool-replace
|
|
.Nd replace one device with another in ZFS storage pool
|
|
.Sh SYNOPSIS
|
|
.Nm zpool
|
|
.Cm replace
|
|
.Op Fl fsw
|
|
.Oo Fl o Ar property Ns = Ns Ar value Oc
|
|
.Ar pool Ar device Op Ar new-device
|
|
.
|
|
.Sh DESCRIPTION
|
|
Replaces
|
|
.Ar device
|
|
with
|
|
.Ar new-device .
|
|
This is equivalent to attaching
|
|
.Ar new-device ,
|
|
waiting for it to resilver, and then detaching
|
|
.Ar 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 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 7
|
|
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 verified 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.
