November 2, 20241 yr Hello. I started my parity check last night and it started around 105-115 MB/s on a 16TB parity drive. This morning when I checked it's down to 25MB/s and I'm not sure why. I'll attach a diagnostics taken during the slow period of parity check. If anyone could help me figure this out I would really appreciate it. Thank you diagnostics-20241102-1114.zip
November 2, 20241 yr Nothing logged about any disk issues, could be a disk with slow sectors, run the diskspeed docker test.
November 2, 20241 yr Author Solution Thank you for the quick reply.. I actually figured it out. Jellyfin container was throwing some gpu transcoding errors for some reason even though it wasn't being used, and I restarted the container and the parity check speed shot right back up to 160MB/s.
