TDA Posted August 8, 2019 Share Posted August 8, 2019 Hello everyone, I'm having a strange behavior with my Unraid 6.7.2 I've isolated CPU0, since is the one used by Unraid itself But despite that I'm having following scenario: The "only" thing PLEX is doing atm is to generate a preview thumbnail for a film I've added.

testdasi Posted August 8, 2019 Share Posted August 8, 2019 You misunderstood isolation. Isolation = tell Unraid (including dockers) to NOT use the core (usually because you want your VM to use it). Isolating CPU0 is almost always not recommended. If you want a docker to not use a certain core, you need to use the docker CPU pinning feature to select which cores the docker can use (and thus if you don't select CPU0 then the docker won't use that core).

Hello, I though that I had to select all 37CPU for PLEX, but since the core is isolated (so it tell Docker to not use it), why is sicker using it? also why isn’t recommended? cheers Quote Link to comment
itimpi Posted August 9, 2019 Share Posted August 9, 2019 UnRAID will always use cpu0 to run any tasks required to support emulation or I/O so not using it for other tasks as well is recommended. Quote Link to comment
