[PHYSICAL DEVICE OPTIONS]

VolumeGroupName PhysicalDevicePath

[PhysicalDevicePath...]

 

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. Moreover, it allows you to
re-add a physical volume that has gone missing previously, due to a transient
device failure, without re-initialising it. Use
vgextend –restoremissing to that effect.


If PhysicalDevicePath was not previously configured for LVM with
pvcreate(8), the device will be initialized with the same
default values used with pvcreate(8). If non-default
pvcreate(8) values are desired, they may be given on the
commandline with the same options as pvcreate(8). See
PHYSICAL DEVICE OPTIONS

for available options. Note that the restore-related options such as
–restorefile, –uuid and –physicalvolumesize

are not available. If a restore operation
is needed, use pvcreate(8) and vgcfgrestore(8).
 

OPTIONS

See lvm(8) for common options.
 

PHYSICAL DEVICE OPTIONS

The following options are available for initializing physical devices in the
volume group. These options are further described in the
pvcreate(8) man page.


-f, –force


-y, –yes


-Z, –zero {y|n}


–labelsector sector


–metadatasize size


–metadataignore {y|n}


–pvmetadatacopies copies


–dataalignment alignment


–dataalignmentoffset alignment_offset



 

Examples

Extends the existing volume group "vg00" by the new physical volumes
(see pvcreate(8)) "/dev/sda4" and "/dev/sdn1".


vgextend vg00 /dev/sda4 /dev/sdn1
