       lvmdump - create lvm2 information dumps for diagnostic purposes


       lvmdump [options] [-d directory]


       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
       - if enabled with -c, cluster status info


       -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

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


              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".
