Using the
-v
argauament with the
lvs
command adds the following fields to the default display:
seg_count
,
lv_major
,
lv_minor
,
lv_kernel_major
,
lv_kernel_minor
,
lv_uuid
.

You can use the
--segments
argument of the
lvs
command to display information with default
columns that emphasize the segment information. When you use the
segments
argument, the
seg
prefix is optional. The
lvs --segments
command displays the following fields by default:
lv_name
,
vg_name
,
lv_attr
,
stripes
,
segtype
,
seg_size
. The default display is sorted by
vg_name
,
lv_name
within the volume group, and
seg_start
within the logical volume. If the
logical volumes were fragmented, the output from this command would show that.
# lvs --segments
LV VG Attr #Str Type SSize
LogVol00 VolGroup00 -wi-ao 1 linear 36.62G
LogVol01 VolGroup00 -wi-ao 1 linear 512.00M

lv vg -wi-a- 1 linear 104.00M
lv vg -wi-a- 1 linear 104.00M
lv vg -wi-a- 1 linear 88.00M
Using the
-v
argument with the
lvs --segments
command adds the following fields to the
default display:
seg_start
,
stripesize
,
chunksize
.
# lvs -v --segments
Finding all logical volumes
LV VG Attr Start SSize #Str Type Stripe Chunk
lvol0 new_vg owi-a- 0 52.00M 1 linear 0 0
newvgsnap1 new_vg swi-a- 0 8.00M 1 linear 0 8.00K
The following example shows the default output of the
lvs
command on a system with one
logical volume configured, followed by the default output of the
lvs
command with the
segments
