I have a problem that i've not seen so far in the forum. In 6.8.3 i had an excessive write problem. It's known and related to partition btrfs. I upgraded to beta30 directly from 6.8.3 Yesterday i received new ssds so i setup a new pool (2 ssd) and make it my cache pool. It stores appdata, domains and system. I continue to have high writes rates on loop2 devices.  https://forums.unraid.net/topic/97902-getting-rid-of-high-ssd-write-rates/ https://forums.unraid.net/bug
