    Command:

    lvmdump

    
    
    

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

    ENVIRONMENT VARIABLES

           LVM_BINARY
                  The LVM2 binary to use.  Defaults to "lvm".  Sometimes you might
                  need to set this to "/sbin/lvm.static", for example.
    
           DMSETUP_BINARY
                  The dmsetup binary to use.  Defaults to "dmsetup".
