Understanding the LVM Configuration Files in Linux
The following files are part of LVM configuration:/etc/lvm/lvm.conf
Central configuration file read by the tools.
etc/lvm/lvm_hosttag.conf
For each host tag, an extra configuration file is read if it exists: lvm_hosttag.conf. If that file defines new tags,
then further configuration files will be appended to the list of tiles to read in.
In addition to the LVM configuration files, a system running LVM includes the following files that affect LVM system setup:
/etc/lvm/cache
Device name filter cache file (configurable).
/etc/lvm/backup/
Directory for automatic volume group metadata backups (configurable).
/etc/lvm/archive/
Directory for automatic volume group metadata archives (configurable with regard to directory path and archive history depth).
/var/lock/lvm/
In single-host configuration, lock files to prevent parallel tool runs from corrupting the metadata; in a cluster, cluster-wide DLM is used.
