Version of this script with latests improvements, still rockin' in 2026 ! (note : I removed transmission section caus' I don't use it, feel free to add it again). #!/bin/bash # This script gets playing sessions from Plex, and tells rsync to copy them from array to cache drive. # It also cleans oldest modified files by rsyncing them back to array (in case of modification). # Hardlink are preserved # # By Reynald mailto:[email protected] # Now works with plex v1.40 or later # WARNING this script must be scheduled carefully one time every 6 minutes max (10 minutes advised), execute it more frequently can damage your SSD # Correction of file permissions by Reynald # By Quinto added analyze of media by plex after syncing to prevent wrong media duration (2hrs bug) # By Quinto Now work with multiple parts movie and with multiple medias movie (eg Same movie in 1080p and 4k) # v.0.6.2 # settings { #Plex # put here the corresponding docker name of your plex App egg binhex-plex, Plex-Media-Server, etc PLEX_DOCKER="Plex-Media-Server" PLEX_TOKEN="xxxxxxxxxxxxxxxxx" PLEX_HOST="192.168.0.240:32400" PLEX_MAX_CACHED_SESSIONS=16 PLEX_CONTAINER_PATH="video_data" #Rsync path & options STORAGE_PATH="/mnt/user0/video_data/" CACHE_PATH="/mnt/plex_smart_cache/video_data/" CACHE_MIN_FREE_SPACE_PCT="94" CACHE_MAX_FREE_SPACE_PCT="60" #Parameters LOG_MAX_SIZE=5000000 NOISY_HOUR_START= NOISY_HOUR_STOP= # if you're not using Youtube-dl agent for plex don't touch this line, it must only be changed when you're using yt-dl custom agent YOUTUBE_DL_AGENT="com.plexapp.agents.youtube-dl" #Options (set to true or false) DRY_RUN=false WRITE_ON_STORAGE=false #number of episodes to cache PLEX_CACHE_NB_EPISODES=6 PLEX_CACHE_SEASON_TILL_END=false VERBOSE=0 #0=Error; 1=Info; 2=More_Info; 3=Debug } ##### No modification below this line ##### CACHE_DISK=$(df -lah "$CACHE_PATH" | awk 'FNR == 2 {print $1}' | tr -d '\n') sys_checks() { # check if plex docker is running plex_running=`docker inspect -f '{{.State.Running}}' $PLEX_DOCKER` if [[ ! $plex_running ]] then echo "Error: Plex docker is not running" rm /var/lock/smart-cache_plex_transmission exit 1 fi # lock if [[ -f /var/lock/smart-cache_plex_transmission ]] then echo "Error: Script already running" rm /var/lock/smart-cache_plex_transmission exit 1 else touch /var/lock/smart-cache_plex_transmission [[ $VERBOSE -ge 2 ]] && echo "Welcome to $0" fi # check that path are mounted if [[ ! -d $STORAGE_PATH ]] || [[ ! -d $CACHE_PATH ]]; then echo "Error: Paths are not accessibles" rm /var/lock/smart-cache_plex_transmission exit 1 fi # cut log LOG_FILE=$(echo $0 | sed 's|\/script|\/log.txt|') echo "log= $LOG_FILE" LOG_SIZE=$(stat -c %s "$LOG_FILE") [[ $VERBOSE -ge 1 ]] && echo "Info: Log size is $LOG_SIZE" if [[ $LOG_SIZE -ge $LOG_MAX_SIZE ]] then [[ $VERBOSE -ge 1 ]] && echo "Info: Emptying log file" echo "" > "$LOG_FILE" fi [[ $VERBOSE -ge 1 ]] && echo "" } ####################### # Transfers functions # ####################### noisy_hours() { # return 0 if time in noisy hour range if [[ $(date '+%-H') -ge $NOISY_HOUR_START ]] && [[ $(date +%-H) -le $NOISY_HOUR_STOP ]] then return 0 else return 1 fi } rsync_transfer() { # get files and path SOURCE_FILE=$1 DEST_FILE=$2 SOURCE_PATH=$3 DEST_PATH=$4 PLEX_ANALYZE_STRING=$5 RS_OPTIONS=$6 [[ $VERBOSE -ge 3 ]] && echo " --- Debug:Rsync_transfer function parameters:" [[ $VERBOSE -ge 3 ]] && echo " ---- Debug: Source file: $SOURCE_FILE" [[ $VERBOSE -ge 3 ]] && echo " ---- Debug: Dest. file: $DEST_FILE" [[ $VERBOSE -ge 3 ]] && echo " ---- Debug: Source path: $SOURCE_PATH" [[ $VERBOSE -ge 3 ]] && echo " ---- Debug: Dest. path: $DEST_PATH" [[ $VERBOSE -ge 3 ]] && echo " ---- Debug: Plex Analyze string: $PLEX_ANALYZE_STRING" [[ $VERBOSE -ge 3 ]] && echo " ---- Debug: Options : $RS_OPTIONS" # check if original file exist if [[ ! -f "${SOURCE_FILE}" ]] && [[ ! -f "${DEST_FILE}" ]] then echo " --- Error: Files:" echo " ${SOURCE_FILE}" echo " ${DEST_FILE}" echo " does not exist" return 1 elif [[ "${DEST_FILE}" = "${DEST_PATH}" ]] || [[ "${SOURCE_FILE}" = "${SOURCE_PATH}" ]] then echo " --- Error: Cannot sync root path!" return 1 elif [[ ! -f "${SOURCE_FILE}" ]] && [[ "${DEST_PATH}" = "${CACHE_PATH}" ]] && [[ -f "${DEST_FILE}" ]] then if noisy_hours then if [[ !

it's NEXUS DOUBLETWIN | HARD DRIVE VIBRATION ISOLATOR : https://silentpc.com/quiet-pc-accessories/doubletwin

ST14000VN0008-2JG101 is the serial number of the involved hard drive, you can try to reseat the sata cable or to change it...

take a look at this thread : https://forums.unraid.net/topic/26050-idenitifying-which-drive-is-quotata9quot-throwing-errors-into-syslog/

it can be bad sata connexion or bad sata cable, or too much vibration during the parity check which can mess with the sata cable, etc...

Just a little update, the script is broken with the latests Plex versions, i'm working on an update, for jellyfin sorry i don't use that at the moment, so, i can't work on it...

yup these are the correct settings, you will notice a slight impact on ram usage but it's hard to notice only with one transoding for only one user...

weird problem, as a temporary workaround you can downgrade to older version if you want, just put "1.29.1.6316-f4cdfea9c-ls139" in the VERSION variable in your Plex docker settings...

can you try with a video with .SRT subtitles ? I think the problem can be PGS subtitles...

i think this video will help you: Unraid - Enabling Intel Quick Sync for Plex Transcoding (and other containers) : https://www.youtube.com/watch?v=tmsXyFVdRAs

do you use "Intel-GPU-TOP" plugin ?

it must be confusion, latest plex version should be : 1.29.1 at first sight your docker settings seems ok, have you ever used specific script to enable quicksync at the start of the plex docker ?

What's the version number of your plex media server ? Can you show us the complete settings of your Plex-Media-Server docker?

all seems normal now, problem is gone after uninstalling "python3.plg" and "python2.plg" and reinstalling python via NerdTools plugin...

Tu devrais te pencher sur les plugins "gpu statistics" et "Radeon-TOP" je pense que tu trouveras ton bonheur...
