Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

NAME
vgcfgbackup - create or update LVM volume group configuration backup file
SYNOPSIS
vg_conf_path] vg_name
DESCRIPTION
The command saves the LVM configuration for a volume group in a default or alternate configuration backup file (see the option).
By default, runs automatically each time an LVM command changes the LVM configuration. In this case, it always uses the default configura-
tion backup file. An existing default configuration backup file is renamed with an extension of
Options and Arguments
recognizes the following options and arguments:
vg_name The path name of a volume group.
Save the configuration using an alternate file name specified by
vg_conf_path.
If is omitted, the default file name is in the form:
base_vg_name is the base name of vg_name. For example, if vg_name is specified as base_vg_name is
Update the configuration backup file with the latest LVM configuration.
Only those physical volumes added since the configuration backup file was last modified need to be online.
If is omitted, all physical volumes for vg_name must be online.
RETURN VALUE
exits with one of the following values:
Successful completion.
Failure.
Errors occurred when information from the volume group was being accessed.
EXTERNAL INFLUENCES
Environment Variables
determines the language in which messages are displayed.
If is not specified or is null, it defaults to "C" (see lang(5)).
If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).
EXAMPLES
Back up LVM configuration information for volume group in the default backup file
Update LVM configuration information corresponding to volume group in the default backup file
Back up LVM configuration information for volume group in the alternate configuration backup file
WARNINGS
It is recommended that any alternate configuration backup file be created in the root file system (as is the case with the default path
name). This facilitates easy volume group recovery during maintenance mode, such as after a system crash.
