NAME

6       lvmdump - create lvm2 information dumps for diagnostic purposes
7

SYNOPSIS

9       lvmdump [options] [-d directory]
10

DESCRIPTION

12       lvmdump  is  a  tool  to  dump  various information concerning LVM2. By
13       default, it creates a tarball suitable  for  submission  along  with  a
14       problem report.
15
16       The content of the tarball is as follows:
17       - dmsetup info
18       - table of currently running processes
19       - recent entries from /var/log/messages (containing system messages)
20       - complete lvm configuration and cache
21       - list of device nodes present under /dev
22       - if enabled with -m, metadata dump will be also included
23       -  if  enabled  with -a, debug output of vgscan, pvscan and list of all
24       available volume groups, physical volumes and logical volumes  will  be
25       included
26       - if enabled with -c, cluster status info
27

OPTIONS

29       -h — print help message
30
31       -a — advanced collection
32              WARNING:  if  lvm  is already hung, then this script may hang as
33              well if -a is used
34
35       -m — gather LVM metadata from the PVs
36              This option generates a 1:1 dump of the metadata area  from  all
37              PVs  visible to the system, which can cause the dump to increase
38              in size considerably. However, the metadata dump may represent a
39              valuable diagnostic resource.
40
41       -d directory — dump into a directory instead of tarball
42              By  default,  lvmdump  will  produce a single compressed tarball
43              containing all the information. Using this  option,  it  can  be
44              instructed  to  only produce the raw dump tree, rooted in direc‐
45              tory.
46
47       -c — if clvmd is running, gather cluster data as well
