I can not get the exclusions to work. Reading through these posts I am pretty confident that I should set it to /docker-sys/.*
I have tried variations on that and also including the cache drive name /nvme_1_nvme/
When I first installed zfs master I had a parent folder above my docker-sys folder. It was /docker/docker-sys/ when this was my folder scheme I remember them being excluded. However I have now removed that parent folder and the docker-sys folder is its own dataset.
I have dozens of these docker images listed.
Only a user for about a year, after deciding to build my own server last year. Looked at many options and once I found unraid I knew the search was over. Everything works great and the helpful forums are full of answers.
Keep up the great work.
