[Version: 6.9.2]  I've been using Unraid for several months on a homebuilt server and have a couple questions about upgrades I'd like to perform this weekend.  I use Unraid primarily for Docker and to host some shares, but most of my data is stored on a Synology Rackstation, so the data on my Unraid shares isn't terribly critical.

 

My array consists of the following:

• 10TB Seagate Ironwolf NAS drive for Parity
• 2 more 10TB Seagate Ironwolf drives
• 3 2TB Seagate Ironwolf drives

 

I have one 1TB SSD in the nvme0n1 slot as a cache drive.

 

I've gotten my mitts on another 10TB Ironwolf and a 2TB M.2 drive.  My mobo is an MSI MAG B550 Tomahawk with two M.2 slots.

 

If I wanted to install the new SSD and use it to store docker info to improve read/write speed, what's the best way to do that?

 

Also, I have no more available slots for HDs, so if I wanted to swap out the 10TB for one of the 2TB, is that as simple as shutting down the array, swapping the drives and then repairing/expanding the volume?

Create another pool for the new M.2
