Merge pull request #696 from iwebhosting/rbd-live-resize
Default to notify only script to handle non-CLVM/QCOW cases.This relates to
[CLOUDSTACK-8732](https://issues.apache.org/jira/browse/CLOUDSTACK-8732)
Before this commit the call to `getResizeScriptType` would throw an exception
(earlier versions returned `null`, which was fine) - this caused the RBD case
to fail. By changing the default to notify only we fix the case for any
non-CLVM and non-QCOW cases, too.
This is RBD for now, but this should extend to new storage types supported by
Libvirt natively in future.
This is my first attempted contribution: I can see a case for adding RBD logic
to the actual getResizeScriptType call, too, but I felt that putting it
`LibvirtResizeVolumeCommandWrapper.java` kept the special-casing of RBD (and
comments about that) in one place.
### Caveat:
With Libvirt 1.2.2 this actually doesn't do the right thing - but it does do
what the documentation *says* should be the right thing, so I'm going to test
if this is a Libvirt bug which is fixed in a later version.
(To make it work I need to execute something like:
virsh blockresize --path vda --size 100G i-7-44-VM
where vda is the path as far as the *guest* is concerned, and not an `rbd/`
path - which *should* work, but doesn't.)
* pr/696:
Default to notify only script to handle non-CLVM/QCOW cases.
