This script automatically spins up all defined Disks to remove spin up latency on playback. It should be executed through CA User Scripts on array startup. This script is inspired by @MJFOx's version. But instead checking the Plex log file, which needs to enable Debugging, this script monitors the CPU load of the Plex container (which rises if a Plex Client has been started): #!/bin/bash # make script race condition safe if [[ -d "/tmp/${0///}" ]] || ! mkdir "/tmp/${0///}"; then exit 1; fi
