DESCRIPTION
vgs produces formatted output about volume groups.

OPTIONS
See lvm for common options.

--all
    List all volume groups. Equivalent to not specifying any volume groups.

--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.

    Use -o vg_all to select all volume group columns.

    Use -o help to view the full list of columns available.

    Column names include: vg_fmt, vg_uuid, vg_name, vg_attr, vg_size, vg_free, vg_sysid, vg_extent_size, vg_extent_count, vg_free_count, max_lv, max_pv, pv_count, lv_count, snap_count, vg_seqno, vg_tags, vg_mda_count, vg_mda_free, and vg_mda_size, vg_mda_used_count.

    Any "vg_" prefixes are optional. Columns mentioned in either pvs (8) or lvs (8) can also be chosen, but columns cannot be taken from both at the same time.

    The vg_attr bits are:

    1   Permissions: (w)riteable, (r)ead-only

    2   Resi(z)eable

    3   E(x)ported

    4   (p)artial: one or more physical volumes belonging to the volume group are missing from the system

    5   Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited

    6   (c)lustered

-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 hHbBsSkKmMgGtTpPeE
    All sizes are output in these units: (h)uman-readable, (b)ytes, (s)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Can also specify custom units e.g. --units 3M

--unquoted
    When used with --nameprefixes, output values in the field=value pairs are not quoted.
