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).

NAME

       vgrename - rename a volume group

SYNOPSIS

       vgrename  [-A|--autobackup{y|n}]  [-d|--debug]  [-h|--help]  [-v|--verbose] { OldVolumeGroupPath NewVolumeGroupPath | OldVolumeName NewVol-
       umeGroupName }

DESCRIPTION

       vgrename renames an existing (see vgcreate(8) ) volume group.

   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 information about vgrename's activities.

Examples
       "vgrename /dev/vg02 /dev/my_volume_group" renames existing volume group "vg02" to "my_volume_group".

       "vgrename vg02 my_volume_group" does the same.

DIAGNOSTICS

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

       1  new volume group directory for device special files already exists
       2  old volume group directory for device special files doesn't exist
       3  new volume group name is invalid
       4  old volume group name is invalid
       5  error checking existence of old volume group
       7  volume group names are identical
       8  new volume group already exists
       9  error reading VGDA
       10 error removing old VGDA from kernel
       11 error removing old VGDA from lvmtab
       12 error removing device special files for old volume group
       13 error creating device special files for new volume group
       14 error inserting new volume group name into lvmtab
       15 error backinp up VGDA
       16 error writing VGDA to lvmtab
       17 error renaming volume group in kernel

       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
