LVMDUMP(8)                                                          LVMDUMP(8)



NAME
       lvmdump -- create lvm2 information dumps for diagnostic purposes

SYNOPSIS
       lvmdump [-a] [-c] [-d directory] [-h] [-l] [-m] [-p] [-s] [-u]

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 /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 -p, lvmpolld state if running
       - if enabled with -s, system info and context
       - 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  information.  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  metadata, 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 vis-
              ible  to  the  system, which can cause the dump to increase in size considerably.  However, the metadata
              dump may represent a valuable diagnostic resource.

       -p     Include lvmpolld(8) daemon dump if it is running. The dump contains all in-progress operation  currently
              monitored  by  the  daemon  and  partial  history  for all yet uncollected results of polling operations
              already finished including reason.

       -s     Gather system info and context. Currently, this encompasses systemd info and context only: 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     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".
