Logging

in the /etc/lvm/backup file and the metadata archives are stored in the /etc/lvm/archive

file. How long the metadata archives stored in the /etc/lvm/archive file are kept and how many

archive files are kept is determined by parameters you can set in the lvm.conf file. A daily system

backup should include the contents of the /etc/lvm directory in the backup.

Note that a metadata backup does not back up the user and system data contained in the logical

volumes.

You can manually back up the metadata to the /etc/lvm/backup file with the vgcfgbackup

command. You can restore metadata with the vgcfgrestore command. The vgcfgbackup and

vgcfgrestore commands are described in Section 4.3.12, “Backing Up Volume Group Metadata”.

3.5. Logging

All message output passes through a logging module with independent choices of logging levels for:

• standard output/error

• syslog

• log file

• external log function

The logging levels are set in the /etc/lvm/lvm.conf file, which is described in Appendix B, The

LVM Configuration Files.
