Linux Command Library


create lvm2 information dumps for diagnostic purposes

lvmdump [-a] [-c] [-d directory] [-h] [-m]

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


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


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.


Print help message


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.


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".
