Hi,
I've ran into a problem when setting up storage spaces on my local WS2012R2 Standard with Essentials Role installed. I've created a storage space with initally 3 disks via the Wizard inside the Dashboard and bought an additional 2 disks.
My data fitted on 2 of the 3 disks, so that I could create an initial storage space with 3 disks. Afterwards I copied my data from the two disks onto the new space and added the now empty 2 disks to the 3 disk pool, resulting in a storage space of five disks. So far so good.
When reviewing my configuration I came to know, that the storage space is running in two-way mirror mode. Since I'm using 5 disks I want to switch this to parity.
How would i be able to do this without additional disks? Currently I've got about 4 TB out of 15TB capacity. Removing disks is not possible. I'm tempted to buy another 4 TB disk for backup at this moment, since in the future I will have even more problems with backing up the ever increasing amount of data. But I would favor it, if I'm able to somehow transfer the data onto a new storage space (or if there will be a possibility to switch the resiliency mode in the future) in parity mode with my existing setup and no additional expenses.
Any suggestions? Maybe via powershell?
kind regards
