the report/output_format setting in lvm.conf.

If there is more than one report per command, each report is prefixed
|
|
with the report name for identification. \fBjson\fP produces report
|
|
output in JSON format. See \fBlvmreport\fP(7) for more information.

\fB-S\fP|\fB--select\fP \fIString\fP
|
|
.br
|
|
Select objects for processing and reporting based on specified criteria.
|
|
The criteria syntax is described by \fB--select help\fP and \fBlvmreport\fP(7).
|
|
For reporting commands, one row is displayed for each object matching the criteria.
|
|
See \fB--options help\fP for selectable object fields.
|
|
Rows can be displayed with an additional "selected" field (-o selected)
|
|
showing 1 if the row matches the selection and 0 otherwise.
|
|
For non-reporting commands which process LVM entities, the selection is
|
|
used to choose items to process.

.ad l
|

\fB-t\fP|\fB--test\fP
|
|
.br
|
|
Run in test mode. Commands will not update metadata.
|
|
This is implemented by disabling all metadata writing but nevertheless
|
|
returning success to the calling function. This may lead to unusual
|
|
error messages in multi-stage operations if a tool relies on reading
|
|
back metadata it believes has changed but hasn't.

.SH VARIABLES
|
|
.HP
|
|
\fIPV\fP
|
|
.br
|
|
Physical Volume name, a device path under /dev.
|
|
For commands managing physical extents, a PV positional arg
|
|
generally accepts a suffix indicating a range (or multiple ranges)
|
|
of physical extents (PEs). When the first PE is omitted, it defaults
|
|
to the start of the device, and when the last PE is omitted it defaults to end.
|
|
Start and end range (inclusive): \fIPV\fP[\fB:\fP\fIPE\fP\fB-\fP\fIPE\fP]...
|
|
Start and length range (counting from 0): \fIPV\fP[\fB:\fP\fIPE\fP\fB+\fP\fIPE\fP]...
|
|
.HP
|
|
\fISelect\fP
|
|
.br
|
|
Select indicates that a required positional parameter can
|
|
be omitted if the \fB--select\fP option is used.
|
|
No arg appears in this position.
|
|
.HP
|
|
\fIString\fP
|
|
.br
|
|
See the option description for information about the string content.
|
|
.HP
|
|
\fISize\fP[UNIT]
|
|
.br
|
|
Size is an input number that accepts an optional unit.
|
|
Input units are always treated as base two values, regardless of
|
|
capitalization, e.g. 'k' and 'K' both refer to 1024.
|
|
The default input unit is specified by letter, followed by |UNIT.
|
|
UNIT represents other possible input units: \fBbBsSkKmMgGtTpPeE\fP.
|
|
b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes,
|
|
m|M is megabytes, g|G is gigabytes, t|T is terabytes,
|
|
p|P is petabytes, e|E is exabytes.
|
|
(This should not be confused with the output control --units, where
|
|
capital letters mean multiple of 1000.)
|
|
.SH ENVIRONMENT VARIABLES
|
|
See \fBlvm\fP(8) for information about environment variables used by lvm.
|
|
For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
|
|
.SH EXAMPLES
|
|
|
|
Disallow the allocation of physical extents on a PV (e.g. because of
|
|
disk errors, or because it will be removed after freeing it).
