vgs (8)

NAME

SYNOPSIS

DESCRIPTION

OPTIONS

--all

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

--aligned

Use with --separator to align the output columns.

--binary

Use binary values "0" or "1" instead of descriptive literal values for columns that have exactly two valid values to report (not counting the "unknown" value which denotes that the value could not be determined).

--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 current list of columns, '-' to remove from the current list of columns or '#' to compact given columns. The -o option can be repeated, providing several lists. These lists are evaluated from left to right.

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, vg_profile, 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

6

(c)lustered, (s)hared

-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.

-S, --select Selection

Display only rows that match Selection criteria. All rows are displayed with the additional "selected" column (-o selected) showing 1 if the row matches the Selection and 0 otherwise. The Selection criteria are defined by specifying column names and their valid values (that can include reserved values) while making use of supported comparison operators. See lvm(8) and -S, --select description for more detailed information about constructing the Selection criteria. As a quick help and to see full list of column names that can be used in Selection including the list of reserved values and the set of supported selection operators, check the output of vgs -S help command.

--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.
