Is it possible to extend PV

Hello,

I have redhat and centos systems that I've only been able to grow the VG by adding more disks. I've been searching the web for a way to extend a volume group by growing the physical disk only and not having to add a second disk. Is it possible?

I can do this with AIX, by just inceasing the size of the underlying LUN, then execute the chvg command. The Volume group will detect the lun increase and that space will be available to the lv and fs without having to reboot.

pvremove

pvremove(1M)															      pvremove(1M)

NAME

       pvremove - remove LVM data structure from a physical volume

SYNOPSIS

DESCRIPTION

       The  command  clears  the LVM data structure on a disk, so that it is no longer an LVM physical volume.	The device may then be used by the
       file system or by other volume managers.

       The operation is denied if pv_path is assigned to a volume group.  The command only clears the LVM data structure on a  disk  if  the  disk
       does not belong to a volume group.  This avoids accidentally removing a valid physical volume under a volume group.  If the physical volume
       to be removed belongs to a volume group, use the command to first remove the volume group associated with the physical volume.

   Arguments
       recognizes the following arguments:

	      pv_path	The character (raw) device path name of a physical volume.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Remove LVM data structure on the physical volume
