Синопсис (Synopsis)
lvmdump [-a] [-c] [-d directory] [-h] [-l] [-m] [-p] [-s] [-u]
Описание (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 (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 -l, lvmetad state if running
• if enabled with -p, lvmpolld state if running
• if enabled with -s, system info and context
• if enabled with -u, udev info and context
Параметры (Options)
-a Advanced collection. WARNING: if lvm is already hung,
then this script may hang as well if -a is used.
-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.
-h Print help message
-l Include lvmetad(8) daemon dump if it is running. The dump
contains cached information that is currently stored in
lvmetad: VG metadata, PV metadata and various mappings in
between these metadata for quick access.
-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.
-p Include lvmpolld(8) daemon dump if it is running. The dump
contains all in-progress operation currently monitored by
the daemon and partial history for all yet uncollected
results of polling operations already finished including
reason.
-s Gather system info and context. Currently, this
encompasses info gathered by calling lsblk command and
various systemd info and context: overall state of systemd
units present in the system, more detailed status of units
controlling LVM functionality and the content of systemd
journal for current boot.
-u Gather udev info and context: /etc/udev/udev.conf file,
udev daemon version (output of 'udevadm info --version'
command), udev rules currently used in the system (content
of /lib/udev/rules.d and /etc/udev/rules.d directory),
list of files in /lib/udev directory and dump of current
udev database content (the output of 'udevadm info
--export-db' command).
