[PhysicalDevicePath...]
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)
.
See lvm(8)
for common 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
Extends the existing
volume group "vg00" by the new physical volumes (see pvcreate(8)
) "/dev/sda4"
and "/dev/sdn1".
