The proof of concept has been going well at Acme Financial Services. Their team are a few sprints in and have just pinged you an email out of the blue:

Ruh roh. Normally this would just be handled via support but you know it might take longer for a response as this isn't technically a production environment. You agree to help Chad to try and prevent any bad news for the proof of concept.

Time to roll up your sleeves, join the Acme Skype for Business™ video call and get it sorted. Tick tock...

## 5.1 - Expand the vm storage
|
|
|
|
For this task your team's challenge is to increase the storage of an existing virtual machine `cryto-carnivore-cpuminer3000` in the `super-important-dont-deleteme` namespace.
|
|
|
|
The virtual machine currently has a root disk of `30GiB` of storage. This needs to be increased to `60GiB`. No command line is required, though you will need to investigate potential storage misconfigurations and verify that your additional storage is now presented to the virtual machine operating system.

## 5.2 - But wait there's more!
|
|
|
|
While you're on the Skype for Business™ video call with Chad fixing the `crypto-carnivore-cpuminer3000` stprage he also puts you on the spot and asks for some guidance on how to add an additional disk to the vm for a new ~~cve-ridden-literal-malware~~workload that Acme is developing.
