   31 .Os
   32 .
   33 .Sh NAME
   34 .Nm zpool-replace
   35 .Nd replace one device with another in ZFS storage pool
   36 .Sh SYNOPSIS
   37 .Nm zpool
   38 .Cm replace
   39 .Op Fl fsw
   40 .Oo Fl o Ar property Ns = Ns Ar value Oc
   41 .Ar pool Ar device Op Ar new-device
   42 .
   43 .Sh DESCRIPTION
   44 Replaces
   45 .Ar device
   46 with
   47 .Ar new-device .
   48 This is equivalent to attaching
   49 .Ar new-device ,
   50 waiting for it to resilver, and then detaching
   51 .Ar device .
   52 Any in progress scrub will be cancelled.
   53 .Pp
   54 The size of
   55 .Ar new-device
   56 must be greater than or equal to the minimum size of all the devices in a mirror
   57 or raidz configuration.
   58 .Pp
   59 .Ar new-device
   60 is required if the pool is not redundant.
   61 If
   62 .Ar new-device
   63 is not specified, it defaults to
   64 .Ar device .
   65 This form of replacement is useful after an existing disk has failed and has
   66 been physically replaced.
   67 In this case, the new disk may have the same
   68 .Pa /dev
   69 path as the old device, even though it is actually a different disk.
   70 ZFS recognizes this.
   71 .Bl -tag -width Ds
   72 .It Fl f
   73 Forces use of
   74 .Ar new-device ,
   75 even if it appears to be in use.
   76 Not all devices can be overridden in this manner.
   77 .It Fl o Ar property Ns = Ns Ar value
   78 Sets the given pool properties.
   79 See the
   80 .Xr zpoolprops 7
   81 manual page for a list of valid properties that can be set.
   82 The only property supported at the moment is
   83 .Sy ashift .
   84 .It Fl s
   85 The
   86 .Ar new-device
   87 is reconstructed sequentially to restore redundancy as quickly as possible.
   88 Checksums are not verified during sequential reconstruction so a scrub is
   89 started when the resilver completes.
   90 Sequential reconstruction is not supported for raidz configurations.
   91 .It Fl w
   92 Waits until the replacement has completed before returning.
   93 .El
   94 .
