.br
The size of the new LV in logical extents. The number of physical extents
allocated may be different, and depends on the LV type, e.g. mirroring.
The number of logical extents can also be expressed as a percentage of the
total space in the Volume Group with the suffix \fB%VG\fP, as a percentage
of the remaining free space in the Volume Group with the suffix
\fB%FREE\fP, as a percentage of the remaining free space for the specified
PhysicalVolume(s) with the suffix \fB%PVS\fP, or (for a snapshot) as a
percentage of the total space in the Origin Logical Volume with the suffix
\fB%ORIGIN\fP (i.e. \fB100%ORIGIN\fP provides space for the whole origin).
When expressed as a percentage, the number is treated as an approximate
upper limit, and the actual size of the LV (in logical extents) may be
less.
Specifies the size of the new LV in logical extents. The number of
physical extents allocated may be different, and depends on the LV type.
Certain LV types require more physical extents for data redundancy or
metadata. An alternate syntax allows the size to be determined indirectly
as a percentage of the size of a related VG, LV, or set of PVs. The
suffix \fB%VG\fP denotes the total size of the VG, the suffix \fB%FREE\fP
the remaining free space in the VG, and the suffix \fB%PVS\fP the free
space in the specified Physical Volumes. For a snapshot, the upper bound
can be expressed as a percentage of the total size of the Origin Logical
Volume with the suffix \fB%ORIGIN\fP (\fB100%ORIGIN\fP provides space for
the whole origin). When expressed as a percentage, the number is treated
as an approximate upper limit, and the final size of the LV is not known
until the command is complete.
