vgextend - add physical volumes to a volume group vgextend [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-t|--test] [-v|--verbose] [ PHYSICAL DEVICE OPTIONS ] VolumeGroupName PhysicalDevicePath [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. If PhysicalDevicePath was not previously configured for LVM with pvcreate (8), the device will be initialized with the same default values used with pvcreate. If non-default pvcreate values are are desired, they may be given on the commandline with the same options as pvcreate. 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 for common options. The following options are available for initializing physical devices in the volume group. These options are further described in the pvcreate man page.
