lvs produces formatted output about logical volumes.
See lvm for common options.
- --aligned
- Use with --separator to align the output columns.
- --nameprefixes
- Add an "LVM2_" prefix plus the field name to the output. Useful
with --noheadings to produce a list of field=value pairs that can be used
to set environment variables (for example, in udev (7) rules).
- --noheadings
- Suppress the headings line that is normally the first line of output.
Useful if grepping the output.
- --nosuffix
- Suppress the suffix on output sizes. Use with --units (except h and H) if
processing the output.
- -o, --options
- Comma-separated ordered list of columns. Precede the list with '+' to
append to the default selection of columns instead of replacing it. Column
names are: lv_uuid, lv_name, lv_attr, lv_major, lv_minor, lv_kernel_major,
lv_kernel_minor, lv_size, seg_count, origin, snap_percent, copy_percent,
move_pv, lv_tags, segtype, stripes, stripesize, chunksize, seg_start,
seg_size, seg_tags, devices, regionsize, mirror_log, modules.
- With --segments, any "seg_" prefixes are optional; otherwise any
"lv_" prefixes are optional. Columns mentioned in vgs (8)
can also be chosen. Use -o help to view the full list of fields
available.
- The lv_attr bits are:
- 1
- Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin,
(p)vmove, (s)napshot, invalid (S)napshot, (v)irtual, mirror (i)mage,
mirror (I)mage out-of-sync, under (c)onversion
- 2
- Permissions: (w)riteable, (r)ead-only
- 3
- Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere,
(i)nherited This is capitalised if the volume is currently locked against
allocation changes, for example during pvmove (8).
- 4
- fixed (m)inor
- 5
- State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid (S)uspended
snapshot, mapped (d)evice present without tables, mapped device present
with (i)nactive table
- 6
- device (o)pen
- --segments
- Use default columns that emphasize segment information.
- -O, --sort
- Comma-separated ordered list of columns to sort by. Replaces the default
selection. Precede any column with - for a reverse sort on that
column.
- --rows
- Output columns as rows.
- --separator Separator
- String to use to separate each column. Useful if grepping the output.
- --unbuffered
- Produce output immediately without sorting or aligning the columns
properly.
- --units hsbkmgtHKMGT
- All sizes are output in these units: (h)uman-readable, (s)ectors, (b)ytes,
(k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes. Capitalise to use
multiples of 1000 (S.I.) instead of 1024. Can also specify custom (u)nits
e.g. --units 3M
- --unquoted
- When used with --nameprefixes, output values in the field=value pairs are
not quoted.
