LVMDUMP(8) System Manager's Manual LVMDUMP(8)

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 included
- if enabled with -c, cluster status info

WARNING: if lvm is already hung, then this script may hang as well if -a is used
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.
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.

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".
