Is there a way when extending an LVM of a VM, while this VM is still running, to make this virtual machine see the extension of his LVM volume without rebooting it?
Lets say I have 5 GB LVM volume with system X running on it (debian squeeze). X is on. I perform an LVextend on my hypervisor, X does not notice its disks have grown unless I reboot X.
Is there away to update something that I can extend X his harddrives while it is live AND not have to reboot it after the extend?
