cowger Posted January 2, 2022 Share Posted January 2, 2022 I'm having a consistent problem streaming ripped BluRay videos from my UnRaid setup, and I'm not really sure where to start. This has been an issue for some time now but seems to be getting worse since installing the latest UnRaid OS. It has mostly been simple audio dropouts in the past but now the video is stuttering which has made watching movies unacceptably bad. My setup is an Intel i3-2100 dual core box with 8 drives connected via a Cisco switch to a Dune HD player. UnRaid OS is 6.9.2. When I copy a movie to the Dune's local HDD and play it from there, it performs flawlessly. Via the network, however, the stutter happens about every 20-40 seconds (fairly random), corresponding with the dropouts in performance shown on the bottom two graphs: Obviously the Network and Storage graphs are highly correlated, and I'm assuming that the Storage is causing the poor performance, but I' not sure. For storage, I have a mix of WD and Seagate drives, including two of the Seagate ST8000DM004 8TB drives. I recently discovered that these are SMR, and I have one as the parity drive (I now realize this is not good), but from what I've read on SMR, it shouldn't be a problem for playback. (I have a new 8TB CMR drive ordered to replace the parity drive, but I have a feeling that this won't solve my video playback issue.) Thank you for any help or ideas on how I can diagnose this issue.
