Watched some videos on the new license option where we can install the license internally on a drive. My question is the only drives I have to use are my two 1 TB SSD NVME drives which are used as cache drives. They are in a pool so both are really just a mirror of the other. IE total 1 TB.

Not an Unraid expert. But what I understand and observe is they are written to first and then the data on those drives is written to my Device drives during the moving phase. My device drives are Sata drives.

With the new licensing option, is it possible to have one of those 1 TB drives still used as a cache drive and the other for the licensing? And since the licensing drive surely does not need an entire 1 TB, still use that remaining space for cache or something else?

Best way to do this would be?

Just to be clear, the license is not tied to the internal boot pool, it can remain tied to the flash drive. It would be used just for licensing, or moved to TPM if the server has that.

Yes my server has that ability, IE. TPM.

I thought one of the benefits was the ability to get rid of that USB Key sticking out from the back of the server by moving to an internal drive. If that is the case, that is what I am hoping I can do. Just in light of what I shared above, how would one achieve that? IE. the steps.

Empty the cache pool by moving everything off, so it can be repartitioned and reformatted.

You would have a mirrored boot partition and another mirrored partition as cache.
