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
−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 directory.
−c — if clvmd is running, gather cluster data as well
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".
