Reports the size of the smallest metadata area in a PV or a VG. Useful to confirm pvcreate --metadatasize or pvmetadatasize setting in /etc/lvm/lvm.conf file. NOTE: Actual value in these fields will most always differ from that given in pvcreate options due to rounding and alignment effects.

.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 \-\-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. Column names are: pv_fmt, pv_uuid,
|
|
pv_size, dev_size, pv_free, pv_used, pv_name, pv_attr, pv_pe_count,
|
|
pv_pe_alloc_count, pv_tags, pvseg_start, pvseg_size, pe_start,
|
|
pv_mda_count, pv_mda_free, and pv_mda_size.
|
|
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.
|
|
Use \fb-o help\fP to view the full list of fields available.
|
|
.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 \-\-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 hsbkmgtHKMGT
|
|
All sizes are output in these units: (h)uman-readable, (s)ectors, (b)ytes,
|
|
(k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes. Capitalise to use multiples
|
|
of 1000 (S.I.) instead of 1024. Can also specify custom (u)nits e.g.
|
|
\-\-units 3M
