lvmdump
LVMDUMP(8) System Manager's Manual LVMDUMP(8)
NAME
lvmdump - create lvm2 information dumps for diagnostic purposes
SYNOPSIS
lvmdump [-a] [-c] [-d directory] [-h] [-l] [-m] [-u]
DESCRIPTION
lvmdump is a tool to dump various information concerning LVM2. By default, it creates a tarball suitable for submission along with a prob-
lem 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 /sys/block
- list of files present /sys/devices/virtual/block
- if enabled with -m, metadata dump will be also 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 -c, cluster status info
- if enabled with -l, lvmetad state if running
- if enabled with -u, udev info and context
OPTIONS
-a Advanced collection. WARNING: if lvm is already hung, then this script may hang as well if -a is used.
-c If clvmd is running, gather cluster data as well.
-d directory
Dump into a directory instead of tarball By default, lvmdump will produce a single compressed tarball containing all the informa-
tion. Using this option, it can be instructed to only produce the raw dump tree, rooted in directory.
-h Print help message
-l Include lvmetad(8) daemon dump if it is running. The dump contains cached information that is currently stored in lvmetad: VG meta-
data, PV metadata and various mappings in between these metadata for quick access.
-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.
-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
LVM_BINARY
The LVM2 binary to use. Defaults to "lvm". Sometimes you might need to set this to "/sbin/lvm.static", for example.
DMSETUP_BINARY
The dmsetup binary to use. Defaults to "dmsetup".
