Unable to Expand FlexClone LUN

Hello,

I'm trying to figure out if it's possible to expand a LUN with a FlexClone Vol. I mirrored the source vol to target a Netapp filer and presented a FlexClone of the mirrored vol to a test server. We are now running into a space issue on the test server and we'd like to expand the drive using SnapDrive, but are unable to. SnapDrive doesn't give us the option to Expand. I assume because it's FlexClone and we'd have to extend the parent volume. Has anybody done this before and if you have could you kindly provide the steps you took.

Thanks!!
