I have Storage Space configured with Parity resiliency that has a total of 5 SATA drives. 4 of the drives are near full capacity (90% used).
I am now getting a low capacity warning because this. I have no more SATA ports available for additional drives (and I don't want to use USB 2.0/USB 3.0), so my plan was to replace two of the existing 2 TB drives with 3 TB drives. As well as a capacity increase, the idea is the during the rebuilding/repairing the remaining 2 TB drives will hopefully be "balanced" a bit, so their usage will be below my custom set threshold of 85%.
As I have parity I can survive one disk being pulled out of the space without any data loss, however I want to perform the swap properly, rather than that simulating hard disk failure by simply pull one drive out.
What steps do I need to take to perform this task? I'm aware I'd need to use PowerShell but I'm looking for specific guidance to ensure that the swap is done correctly. I'm thinking I'll also need to do this with one disk at time, otherwise I'll lose the pool.
