lvm2/man/pvs.8.in
snitzer 69da2ac0c7 Continue to make --units and --size consistent (in code and man pages):
Update units_to_bytes() to support (S)ectors: 500 bytes.
- 500 byte (S)ectors is of questionable value but it adds to consistency
  if a user happens to use --units S.  This seems better than an error.

Updated test/t-covercmd.sh to test --units [hS]

Document the units that can be displayed via --units uniformly.
- (p)etabytes and (e)xabytes were missing in pvs, vgs and lvs man pages.

Made lvreduce man page "... in units of megabytes." consistent (with the
lvextend and lvresize man pages).

.SH DESCRIPTION
pvs produces formatted output about physical volumes.
.SH OPTIONS
See \fBlvm\fP for common options.
.TP
.I \-\-aligned
Use with \-\-separator to align the output columns.
.TP
.I \-\-nameprefixes
Add an "LVM2_" prefix plus the field name to the output. Useful
with --noheadings to produce a list of field=value pairs that can
be used to set environment variables (for example, in \fBudev (7)\fP rules).
.TP
.I \-\-noheadings
Suppress the headings line that is normally the first line of output.
Useful if grepping the output.
.TP
.I \-\-nosuffix
Suppress the suffix on output sizes. Use with \-\-units (except h and H)
if processing the output.
.TP
.I \-o, \-\-options
Comma-separated ordered list of columns. Precede the list with '+' 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, pvseg_start, and pvseg_size.
.IP
With --segments, any "pvseg_" prefixes are optional; otherwise any
"pv_" prefixes are optional. Columns mentioned in \fBvgs (8)\fP can also
be chosen. The pv_attr bits are: (a)llocatable and e(x)ported.
.TP
.I \-\-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
.I \-O, \-\-sort
Comma-separated ordered list of columns to sort by. Replaces the default
selection. Precede any column with - for a reverse sort on that column.
.TP
.I \-\-rows
Output columns as rows.
.TP
.I \-\-separator Separator
String to use to separate each column. Useful if grepping the output.
.TP
.I \-\-unbuffered
Produce output immediately without sorting or aligning the columns properly.
.TP
.I \-\-units hHbBsSkKmMgGtTpPeE
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
.I \-\-unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
