The --binary option, if used, causes all the binary values reported in reporting commands to be displayed as "0" or "1" instead of descriptive literal values (value "unknown" is still used for values that could not be determined). Also, add report/binary_values_as_numeric lvm.conf option with the same functionality as the --binary option (the --binary option prevails if both --binary cmd option and report/binary_values_as_numeric lvm.conf option is used at the same time). The report/binary_values_as_numeric is also profilable. This makes it easier to use and check lvm reporting command output in scripts.

.SH DESCRIPTION
|
|
vgs produces formatted output about volume groups.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP(8) for common options.
|
|
.TP
|
|
.B \-\-all
|
|
List all volume groups. Equivalent to not specifying any volume groups.
|
|
.TP
|
|
.B \-\-aligned
|
|
Use with \fB\-\-separator\fP to align the output columns.
|
|
.TP
|
|
.B \-\-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).
|
|
.TP
|
|
.B \-\-nameprefixes
|
|
Add an "LVM2_" prefix plus the field name to the output. Useful
|
|
with \fB\-\-noheadings\fP to produce a list of field=value pairs that can
|
|
be used to set environment variables (for example, in \fBudev\fP(7) rules).
|
|
.TP
|
|
.B \-\-noheadings
|
|
Suppress the headings line that is normally the first line of output.
|
|
Useful if grepping the output.
|
|
.TP
|
|
.B \-\-nosuffix
|
|
Suppress the suffix on output sizes. Use with \fB\-\-units\fP
|
|
(except h and H) if processing the output.
|
|
.TP
|
|
.BR \-o ", " \-\-options
|
|
Comma-separated ordered list of columns. Precede the list with '+' to append
|
|
to the default selection of columns.
|
|
.IP
|
|
Use \fB\-o vg_all\fP to select all volume group columns.
|
|
.IP
|
|
Use \fB\-o help\fP to view the full list of columns available.
|
|
.IP
|
|
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.
|
|
.IP
|
|
Any "vg_" prefixes are optional. Columns mentioned in either \fBpvs\fP(8)
|
|
or \fBlvs\fP(8) can also be chosen, but columns cannot be taken from both
|
|
at the same time.
|
|

.TP

|
.BR \-O ", " \-\-sort
|
|
Comma-separated ordered list of columns to sort by. Replaces the default
|
|
selection. Precede any column with '\fI\-\fP' for a reverse sort on that
|
|
column.
|
|
.TP
|
|
.B \-\-rows
|
|
Output columns as rows.
|
|
.TP
|
|
.BR \-S ", " \-\-select " " \fISelection
|
|
Display only rows that match Selection criteria. All rows are displayed with
|
|
the additional "selected" column (\fB-o selected\fP) 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 \fBlvm\fP(8)
|
|
and \fB\-S\fP, \fB\-\-select\fP 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 \fBvgs -S help\fP command.
|
|
.TP
|
|
.B \-\-separator \fISeparator
|
|
String to use to separate each column. Useful if grepping the output.
|
|
.TP
|
|
.B \-\-unbuffered
|
|
Produce output immediately without sorting or aligning the columns properly.
|
|
.TP
|
|
.B \-\-units \fIhHbBsSkKmMgGtTpPeE
|
|
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
|
|
.TP
|
|
.B \-\-unquoted
|
|
When used with \fB\-\-nameprefixes\fP, output values in the field=value
|
|
pairs are not quoted.
