LVMDUMP(8)     (LVM TOOLS 2.03.11(2) (2021-01-08))     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 submis-
          sion 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 -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.

          -d directory
               Dump into a directory instead of tarball By default,
               lvmdump will produce a single compressed tarball con-
               taining 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

     LVMDUMP(8)     (LVM TOOLS 2.03.11(2) (2021-01-08))     LVMDUMP(8)

               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 rep-
               resent a valuable diagnostic resource.

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

          -s   Gather system info and context. Currently, this encom-
               passes info gathered by calling lsblk command and vari-
               ous 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   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 (con-
               tent of /lib/udev/rules.d and /etc/udev/rules.d direc-
               tory), 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 "/usr/lvm/lvm.static",
               for example.

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