Increasing memory didn't work

[bolshi]

Hi, I am running Parallels 11 for Mac Bussiness Edition. I shut down my Ubuntu VM. Under configuration -> Hardware -> Hard disk -> configure I set memory size of 20GB to 40GB. After rebooting my Ubuntu VM is still 20GB.

What went wrong?

I am running OS X Sierra ( 10.12.2 )

Hi, did you get any error message during the disk increasing?

Hi, didn't get any error message. I shut down the VM, increase the HDD memory, save it and restarted the VM. Unfortunately the same size :/

And how about Ubuntu resizing tools?
