NAME
lvm - LVM2 tools
SYNOPSIS
lvm [
command
|
file
]
DESCRIPTION
lvm provides the
command
-line tools
for
LVM2. A separate manual page describes each
command
in
detail.
If lvm is invoked with no arguments it presents a readline prompt (assuming it was compiled with readline sup-
port). LVM commands may be entered interactively at this prompt with readline facilities including
history
and
command
name and option completion. Refer to readline(3)
for
details.
If lvm is invoked with argv[0]
set
to the name of a specific LVM
command
(
for
example by using a hard or soft
link) it acts as that
command
.
On invocation, lvm requires that only the standard
file
descriptors stdin, stdout and stderr are available. If
others are found, they get closed and messages are issued warning about the leak.
Where commands take VG or LV names as arguments, the full path name is optional. An LV called
"lvol0"
in
a VG
called
"vg0"
can be specified as
"vg0/lvol0"
. Where a list of VGs is required but is left empty, a list of all
VGs will be substituted. Where a list of LVs is required but a VG is given, a list of all the LVs
in
that VG
will be substituted. So lvdisplay vg0 will display all the LVs
in
"vg0"
. Tags can also be used - see --addtag
below.
One advantage of using the built-
in
shell is that configuration information gets cached internally between com-
mands.
A
file
containing a simple script with one
command
per line can also be given on the
command
line. The script
can also be executed directly
if
the first line is
