.SH DESCRIPTION
pvs produces formatted output about physical volumes.
.SH OPTIONS
See \fBlvm\fP(8) for common options.
.TP
.B \-\-all
Include information in the output about devices that have not been
initialized with \fBpvcreate\fP(8).
.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 pv_all\fP to select all physical volume columns,
and \fB-o pvseg_all\fP to select all Physical Volume segment columns.
.IP
Use \fB-o help\fP to view the full list of columns available.
.IP
Column names include: pv_fmt, pv_uuid, dev_size, pv_name, pv_mda_free,
pv_mda_size, pv_ba_start, pv_ba_size, pe_start, pv_size, pv_free, pv_used,
pv_attr, pv_pe_count, pv_pe_alloc_count, pv_tags, pv_mda_count,
pv_mda_used_count, pvseg_start, and pvseg_size
.IP
With \fB\-\-segments\fP, any "pvseg_" prefixes are optional; otherwise any
"pv_" prefixes are optional.  Columns mentioned in \fBvgs\fP(8) can also
be chosen. The pv_attr bits are: (a)llocatable, e(x)ported and (m)issing.
.TP
.B \-\-segments
Produces one line of output for each contiguous allocation of space on each
Physical Volume, showing the start (pvseg_start) and length (pvseg_size) in
units of physical extents.
.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 \fBpvs -S help\fP command.
.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
.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.
