Physically reinstalled the Bluray drive (different sata port etc) and now it seems to work. Went from sr0 | sg3 to sr0 | sg1. root@Tower:~# docker exec MakeMKV lsscsi -g -k ...

Thanks!

I'll take a look at this when I get home. I also noticed that my initial cache pool refused to be raid 1 (I had to go back down to two drives, and then readd the second drive before raid 1 started). I think the UI needs to be much clearer with what's going on (or the code not break in the first place). Going to all the expense and effort of a second cache drive... to find out it's not even working isn't fun.

Hi Djoss, Similar issue to what Tergo247 faced, albeit this is my first time running unraid/makemkv. root@Tower:~# docker exec MakeMKV lsscsi -g -k ...
