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 prob-
       lem 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

       -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
