.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 \-\-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 '\fI+\fP'
to append to the default selection of columns.
.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, 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 \-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.
