Remove the specified device \fIPhysicalVolume\fP and replace it with one
that is available in the VG, or from a specific list of PVs specified on
the command line following the LV name. This option may be repeated multiple
times depending on the RaidLV type. Maxima for raid1 are N-1 mirrors,
for raid4/5 1 stripe, for raid6 2 stripes and for raid10 it is the number
of stripes, i.e. one mirror in each mirror group. It is recommended to keep
resilience whilst replacing PVs whenever possible, i.e. only replace a maximum
of N-2 mirrors in a raid1 LV and 1 stripe in a raid6 LV at a time;
this is not possible with raid4/5/10 LVs, because any single replaced PV
will render the RaidLV non-resilient against another PV failure during replacement.

.IR Number

Specifies the number of stripes in a striped LV. This is the number of
physical volumes (devices) across which to spread a striped LV. Data that
physical volumes (devices) a striped LV is spread across. Data that
appears sequential in the LV is spread (striped) across multiple devices
in units of the stripe size (see below). This does not apply to existing
allocated space, only newly allocated space can be striped.
