so i notice whenever i use btrfs as my main storage format, PLEX will always keep my volume utilization at 100%.
i was not doing much, other than occasionally add some movie/tv shows.
and PLEX will be fine for a moment when it just starts, but after a while, it will keep volume utilization at 100%. if i then switch off PLEX, volume utilization will immediately drops to <10%. then, if i start PLEX again, everything will happen again.....
I'm using a DS3615xs, 12*6tb red (RAID 5, btrfs), xeon E3 CPU (upgraded from stock i3, but the same problem with i3), so performance of the box shouldn't be an issue.
also, i notice if i use the exactly same setup, except change btrfs to old school ext4, volume utilization will only hit 100% for a short period of time and then return to normal....
anyone else having the same problem? any advice.
