How do you extend the PV then? For example extend the LUN on storage
or just resize a RAID1+0 set by adding 2 new disks... Resizing the
block device is no problem, resizing the PV also, but to resize the
PV, you need to resize the partition also - and if I remember well,
the kernel won't re-read the new partition table while it is used...
