# [DESCRIPTION](#DESCRIPTION)

lvmdump is a tool to dump various information concerning LVM2. By default, it creates a tarball suitable for submission along with a problem report.

The content of the tarball is as follows:

•

dmsetup info

•

table of currently running processes

•

recent entries from */var/log/messages* (containing system messages)

•

complete lvm configuration and cache (content of */etc/lvm*)

•

list of device nodes present under */dev*

•

list of files present in */sys/block*

•

list of files present in */sys/devices/virtual/block*

•

if enabled with -m, metadata dump will also be included

•

if enabled with -a, debug output of vgscan, pvscan and list of all available volume groups, physical volumes and logical volumes will be included

•

if enabled with -l, lvmetad state if running

•

if enabled with -p, lvmpolld state if running

•

if enabled with -s, system info and context

•

if enabled with -u, udev info and context

# [OPTIONS](#OPTIONS)

[**-a**](#a)

Advanced collection.  
**WARNING**: if lvm is already hung, then this script may hang as well if **-a** is used.

[**-d** *directory*](#d)

Dump into a directory instead of a tarball By default, lvmdump will produce a single compressed tarball containing all the information. Using this option, it can be instructed to only produce the raw dump tree, rooted in *directory*.

[**-h**](#h)

Print help message

[**-l**](#l)

Include [**lvmetad**(8)](/man/os/lvm2/lvmetad.8) daemon dump if it is running. The dump contains cached information that is currently stored in lvmetad: VG metadata, PV metadata and various mappings in between these metadata for quick access.

[**-m**](#m)

Gather LVM metadata from the PVs This option generates a 1:1 dump of the metadata area from all PVs visible to the system, which can cause the dump to increase in size considerably. However, the metadata dump may represent a valuable diagnostic resource.

[**-p**](#p)

Include [**lvmpolld**(8)](/man/os/lvm2/lvmpolld.8) daemon dump if it is running. The dump contains all in-progress operations currently monitored by the daemon and partial history for all yet uncollected results of polling operations already finished, including the reason for finishing.

[**-s**](#s)

Gather system info and context. Currently, this encompasses info gathered by calling lsblk command and various systemd info and context: overall state of systemd units present in the system, more detailed status of units controlling LVM functionality and the content of systemd journal for current boot.

[**-u**](#u)

Gather udev info and context: */etc/udev/udev.conf* file, udev daemon version (output of 'udevadm info --version' command), udev rules currently used in the system (content of */lib/udev/rules.d* and */etc/udev/rules.d* directory), list of files in /lib/udev directory and dump of current udev database content (the output of 'udevadm info --export-db' command).

# [ENVIRONMENT VARIABLES](#ENVIRONMENT_VARIABLES)

[**LVM\_BINARY**](#LVM_BINARY)

[**DMSETUP\_BINARY**](#DMSETUP_BINARY)

The dmsetup binary to use. Defaults to "**dmsetup**".
