LVM configuration files

[gany59]

Hi folks,

Can any body tell, what are all the LVM configuration files are there, and what is the need of that file..

Thanks in advance!

If in /etc/lvmconf, then it is a binary VG metadata save file for every VG that is sourced by vgcfgrestore in order to restore the LVM metadata to a disk after corruption or replacement has occurred.

Example /etc/lvmconf/vg00.conf

This file is created whenever a VG is created or modified.

It contains entire lvm metadata ,VG information & headers,LE to PE mapping table,lv names & can restore the full lvm information on the failed disk & then you can just sink the mirrors or restore data from backups.

Hope this helps.

Thanks
Manix
