I think this probably only works in the case that the raw free space is
phyically located beside the specified partition, imagine there are sda1,
sda2 in sequence, when new space
available, resize only possible to sda2, and with a disk with 4 primary
partitions, this won't help either..  am I  right?   ~

resize didn't work for me, I backup my data, and recreated the partition
with a new size, old way but make more sense to me. thanks so much, I'll try
it later in another VM in my office.
