LVM(8)

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 support). 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.

One advantage of using the built-in shell is that configuration information is cached internally between commands.

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 #! followed by the absolute path of lvm.

OPTIONS
The following options can be used with every command and are not documented on individual manual pages.

-h | --help — Display the help text.

--version — Display the version.
    Not implemented yet.

-v | --verbose — Set verbose level.
    Repeat from 1 to 3 times to determine the detail of messages sent to stdout and stderr. Overrides config file setting.

-d | --debug — Set debug level.
    Repeat from 1 to 6 times to determine the detail of messages sent to the log file and/or syslog (if configured). Overrides config file setting.

--quiet — Suppress output and log messages.
    Overrides -d and -v.
