lvs produces formatted output about logical volumes.


See lvm for common options.
 Use with --separator to align the output columns.
 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).
 Suppress the headings line that is normally the first line of output. Useful if grepping the output.
 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
 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.
 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
 When used with --nameprefixes, output values in the field=value pairs are not quoted.
