NAME
vgcfgrestore - display or restore LVM volume group configuration from backup file
SYNOPSIS
/usr/sbin/vgcfgrestore -n
vg_name -l [-v]
/usr/sbin/vgcfgrestore [-R] [-F] -n
vg_name [-o old_pv_path] pv_path
/usr/sbin/vgcfgrestore -f
vg_conf_path -l [-v]
/usr/sbin/vgcfgrestore [-R] [-F] -f
vg_conf_path [-o old_pv_path] pv_path
Remarks
vgcfgrestore cannot be performed if the volume group is activated in shared mode.
vgcfgrestore cannot be performed on devices attached to activated volume groups. Prior to restoring
a backup configuration to a disk, detach the PV from the volume group using the pvchange(1M) command,
or deactivate the volume group using the vgchange(1M) command.
DESCRIPTION
The
vgcfgrestore command restores the LVM configuration data from a default (-n
option) or alter-
nate (
-f option) configuration backup file to the physical volume named by pv_path. Or, it displays the
configuration data on standard output (
-l option).
The configuration stored for one physical volume, old_pv_path, can be copied to another physical volume
pv_path (-o option).
Options and Arguments
vgcfgrestore recognizes the following options and arguments:
pv_path The raw (character) device path name of a physical volume that is currently online.
If the -o option is omitted, pv_path must specify a physical volume whose configuration
is stored in the configuration backup file.
-f vg_conf_path
Get configuration information from the alternate configuration backup file vg_conf_path.
-F This option will force restoring the LVM configuration data even if the physical volume
has alternate block(s) allocated inside the user data area. This option should be used
with extreme caution. User is advised to fix the problem because potential data corrup-
tion could occur.
-l List the configuration information saved in the specified configuration backup file.
-n vg_name
Get configuration information from the default configuration backup file:
/etc/lvmconf/ base_vg_name.conf
vg_name is the path name of the volume group.
base_vg_name is the base name of vg_name. For example, if vg_name is specified as
/dev/vg00, base_vg_name is vg00.
-o old_pv_path
Restore the configuration information saved for physical volume old_pv_path to physical
volume pv_path.
This option is useful when a physical volume’s name has changed since the configuration
backup file was created or updated.
old_pv_path must be the path name of a physical volume whose configuration is stored in
the configuration backup file. It need not be currently online.
pv_path must be the path name of a physical volume that is currently online. Its
configuration need not be stored in the configuration backup file.
