n Do not back up configuration changes this time.
-l Increase the space, specified in logical extents, allocated to the logical
volume or snapshot volume.
-l le_number
increases the space allocated to the logical volume, specified in logi-
cal extents. le_number is a decimal value greater than the current
number of logical extents.
le_number must be at least 1 and no greater than a volume group
version-dependent maximum; use the
lvmadm command to deter-
mine the maximum number of logical extents for the volume group
version.
-l prealloc_le_number
increases the space allocated to the space-efficient snapshot volume,
specified in logical extents.
prealloc_le_number is a decimal value greater than the current
number of preallocated extents, including any unshared number of
extents (if any) for this snapshot volume.
prealloc_le_number can range from 1 to the number of extents occu-
pied by the original logical volume.
One, and only one,
-l, -L,or-m option must be supplied. (The
-m
option is not applicable for snapshot volumes.)
-L Increase the space, specified in megabytes, allocated to the logical
volume or snapshot volume.
-L lv_size
increases the space allocated to the logical volume, specified in
megabytes. lv_size is a decimal value greater than the current logi-
cal volume size.
lv_size must be at least 1 and no greater than a volume group
version-dependent maximum; use the
lvmadm command to deter-
mine the maximum logical volume size for the volume group ver-
sion.
lv_size is rounded up to the nearest multiple of the logical extent
size, equivalent to the physical extent size defined for the volume
group by the
vgcreate command (see vgcreate (1M)).
-L prealloc_le_size
increases the space allocated to the space-efficient snapshot volume,
specified in megabytes.
prealloc_le_size is a decimal value greater than the current preallo-
cated extent size, including the size of any unshared extent size (if
any) for this snapshot volume. prealloc_le_size can range from 1 to
the size of the original logical volume.
prealloc_le_size is rounded up to the nearest multiple of the logical
extent size, equivalent to the physical extent size defined for the
volume group by the
vgcreate command (see vgcreate (1M)).
One, and only one,
-l, -L,or-m option must be specified. (The -m
option is not applicable for snapshot volumes.)
-m mirror_copies Set the number of mirror copies allocated for each logical extent. A mir-
ror copy contains the same data as the original.
mirror_copies must be at least 1 and no greater than a volume group
version-dependent maximum; use the
lvmadm command to determine
the maximum number of mirror copies for the volume group version.
mirror_copies must be greater than the current value.
