Interesting... I tried increasing the size of a LV on which a virtual machine KVM is executed. Then with the operating system running, I umount (although I have understood that it is not necessary) the filesystem /space of the VM and I extended it so that it occupied all the free space. Then I did resize of the extended partition and mounted again /space, but still I continued seeing the old size. I tried doing reboot and shutdown/start of the VM and I get the same result. Peculiarly, starting a VM with a ISO of SystemRescueCD aiming to LV of the VM, when mounting the resized partition yes I saw with the correct size. Booting once again the VM, I saw the partition with the correct size. I do not believe that it has been something of filesystem cache of the VM (because I suppose that after the boot it would have to display the correct size). Perhaps some cache of hardware RAID on which is the LVM filesystem? Thanks for your reply.
