it's a bit odd but basically i'm using flash drive 'A'
4 months ago i suspected it was having issues to i transferred the license to drive 'B' (which is what the license GUID is showing)
but i left the server for a while and when i got it out to recommission it, i plugged in drive 'A' and everything worked like normal from then until just now, after upgrading to 6.9 unraid UI is now showing blacklisted and i cannot start my array.
I realise the drive was technically blacklisted this whole time, but i'm rather annoyed it took unraid 4 months to make it an issue and only after an upgrade, as in that 4 months i now no longer have drive 'B' which has the license attached to it. and of course i can't change it online
