NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore  [-d|--debug]  [-f|--file  <filename>] [--force] [-l[l]|--list] [-h|--help] [-M|--metadatatype 1|2] [-t|--test] [-v|--verbose]
       VolumeGroupName

DESCRIPTION

       vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by  vgcfgbackup.   You  can	specify  a
       backup  file  with --file.  If no backup file is specified, the most recent one is used.  Use --list for a list of the available backup and
       archive files of VolumeGroupName.

OPTIONS

       See lvm(8) for common options.

       -l, --list
	      List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName.  May be used with the
	      -f option.  Does not restore VolumeGroupName.

       -f, --file filename
	      Name  of	LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName.	Often this
	      file has been created with vgcfgbackup.

       --force
	      Necessary to restore metadata with thin pool volumes.
	      WARNING: Use with extreme caution.  Most changes to thin metadata cannot be reverted.  You may lose data	if  you  restore  metadata
	      that does not match the thin pool kernel metadata precisely.

REPLACING PHYSICAL VOLUMES

       vgdisplay  --partial  --verbose will show you the UUIDs and sizes of any PVs that are no longer present.  If a PV in the VG is lost and you
       wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate)	to
       initialise  it with the same UUID as the missing PV.  Repeat for all other missing PVs in the VG.  Then use vgcfgrestore --file filename to
       restore the volume group's metadata.

NAME

       vgextend - add physical volumes to a volume group

SYNOPSIS

       vgextend [-A|--autobackup{y|n}] [-d|--debug] [-h|--help] [-v|--verbose] VolumeGroupName PhysicalVolumePath [PhysicalVolumePath...]

DESCRIPTION

       vgextend allows you to add one or more initialized physical volumes ( see pvcreate(8) ) to an existing volume group to extend it in size.

   OPTIONS
       -A, --autobackup y/n
	      Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes.

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Gives verbose runtime information about lvextend's activities.

Examples
       "vgextend  vg00	/dev/sda4  /dev/sdn1"  tries  to  extend  the  existing volume group "vg00" by the new physical volumes (see pvcreate(8) )
       "/dev/sdn1" and /dev/sda4".

DIAGNOSTICS

       vgextend returns an exit code of 0 for success and > 0 for error:

       1  no volume group name on command line
       2  volume group name not given as first argument
       3  no physical volume(s) on command line
       4  invalid volume group name
       5  error checking existence of volume group
       6  inactive volume group
       7  error reading VGDA
       8  volume group is set to not extendable
       9  maximum physical volume number of volume group exceeded
       10 error reading all physical volumes
       11 error setting up VGDA
       12 error extending VGDA in kernel
       13 error writing VGDA to physical volume(s)

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

ENVIRONMENT VARIABLES

       LVM_AUTOBACKUP
	      If this variable is set to "no" then the automatic backup of VG metadata is turned off.

       LVM_VG_MAX_BACKUPS
	      This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It  can  be  set  to  a  positive  number
	      between 0 and 999.  The higher this number is, the more changes you can restore using vgcfgrestore(8).
