.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, ba_start, 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 \-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.
