Chapter 6. LVM Troubleshooting
This chapter provide instructions for troubleshooting a variety of LVM issues.
6.1. Troubleshooting Diagnostics
If a command is not working as expected, you can gather diagnostics in the following ways:
- Use the
-v
,-vv
,-vvv
, or-vvvv
argument of any command for increasingly verbose levels of output. - If the problem is related to the logical volume activation, set 'activation = 1' in the 'log' section of the configuration file and run the command with the
-vvvv
argument. After you have finished examining this output be sure to reset this parameter to 0, to avoid possible problems with the machine locking during low memory situations. - Run the
lvmdump
command, which provides an information dump for diagnostic purposes. For information, see thelvmdump
(8) man page. - Execute the
lvs -v
,pvs -a
ordmsetup info -c
command for additional system information. - Examine the last backup of the metadata in the
/etc/lvm/backup
file and archived versions in the/etc/lvm/archive
file. - Check the current configuration information by running the
lvm dumpconfig
command. - Check the
.cache
file in the/etc/lvm
directory for a record of which devices have physical volumes on them.
