NAME
       lvmdump - create lvm2 information dumps for diagnostic purposes

SYNOPSIS
       lvmdump [options] [-d directory]

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
       - list of device nodes present under /dev
       - 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
       -h -- print help message

       -a -- advanced collection
	      WARNING: if lvm is already hung, then this script may hang as well if -a is used

       -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.

       -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.

       -c -- if clvmd is running, gather cluster data as well

ENVIRONMENT VARIABLES
       LVM_BINARY
