I'm currently testing 4.0 and trying understand what the capabilities are regards re-sizing of volumes on running VMs.

From reading the documentation it appears that I should be able to extend a volume on a running VM, but I find that all the fields are greyed out in the Edit Virtual Disk dialogue box. In order to get access to the fields I have to power down the VM.

Is this expected behavior?

I'm running 4.0.1 with a GlusterFS data store.

Thanks,

Alan
