NAME

       lvmdump - create lvm2 information dumps for diagnostic purposes

SYNOPSIS

       lvmdump [-a] [-c] [-d directory] [-h] [-m]

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

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

       -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.

ENVIRONMENT VARIABLES

       LVM_BINARY
