I'm trying to build a VM for the Azure Marketplace. My question are about storage solutions. The starting point is an E2as_v4 VM, which comes with about 32 GB for the OS plus 30 GB for data, which I have already filled not even halfway my target configuration. Regarding these 2 disks, my first 2 questions are:
Q1 - The OS disk is almost empty (1 % used), which seems almost a waste. I don't know if this is because Windows is more space hungry than a Linux distro but I was wondering if this free space could be used for anything else. [NOTE: If the empty space is not billed, maybe it doesn't matter but still curious about it]
Q2 - I haven't been able to figure out which performance tier the data disk belongs to.
I need to attach extra space and planning on attaching a 64 GB (P6) disk to begin. The preferred final configuration would be a single data disk (in this example of about 96 GB). I understand that the extra space needs to be formatted and mounted. My questions are:
Q3 - Can I accomplish this objective with fdisk and mkfs or would I need to use any special tool?
Q4 - Because the original data disk and the new one probably belong to different performance tier, how do I control the performance tier of the final disk?
As I mentioned, the final goal is to publish it in the Marketplace:
Q5 - Which special considerations should I keep in mind given the final objective?
