UnRAID: Data, Cache, and the Mover

So I’ll say up front, it’s possible that I haven’t set my storage up in the optimum way, and that choosing ‘just’ a 500GB cache drive has caused me some small issues, but I think that in daily operation, things should be fine.

My biggest challenge with the transition to the new machine was always going to be moving the data from old to new, whilst keeping the old one running and serving media.
As it transpired, we’ve had some internet issues over the last week which has meant the Plex server has been inaccessible to the outside world most of the time anyway, but I had already hatched a plan and that was what I stuck to.

I had 4x6TB (not 4x4TB as I said in my first post) in my Windows machine configured in Windows Storage Spaces. Due to the way it was configured, I could only remove one of the disks, despite having just over 1 disk-worth of data.
Therefore I’d need to move everything before I could destroy the array on my Windows machine and move the other disks.

The cache drive was a savior here, both in terms of storage and speed.
