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
