.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.
|
|
.IP
|
|
Precede the list with '\fI+\fP' to append to the current list
|
|
of columns, '\fI-\fP' to remove from the current list of columns
|
|
or '\fI#\fP' to compact given columns. The \fI\-o\fP option can
|
|
be repeated, providing several lists. These lists are evaluated
|
|
from left to right.
|
|
.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.
|
|
.IP
|
|
The vg_attr bits are:
|
|
.RS
|
|
.IP 1 3
|
|
Permissions: (w)riteable, (r)ead-only
|
|
.IP 2 3

|
Resi(z)eable
|
|
.IP 3 3
|
|
E(x)ported
|
|
.IP 4 3
|
|
(p)artial: one or more physical volumes belonging to the volume group
|
|
are missing from the system
|
|
.IP 5 3
|
|
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere
|
|
.IP 6 3
|
|
(c)lustered, (s)hared

.RE
|
|
.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.
