lvmdump --- create lvm2 information dumps for diagnostic purposes


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


   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
   - 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


   -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 visible to the system,
          which can cause the  dump  to  increase  in  size  considerably.
          However,  the  metadata dump may represent a valuable diagnostic

   -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 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     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).


          The LVM2 binary to use.  Defaults to "lvm".  Sometimes you might
          need to set this to "/sbin/lvm.static", for example.

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