Disable Thumbd Daemon on Synology DiskStation

I have no need for the FileStation app to generate thumbnails of the content I store on my Synology Diskstation NAS, but when I looked at what was running, it spun up several daemons anyway:

6790 ? Ssl 0:00 /var/packages/FileStation/target/sbin/thumbd
6792 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6793 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6818 ? Ssl 0:13 /var/packages/CloudSync/target/sbin/syno-cloud-syncd /volume1/@cloudsync/config/daemon.conf
6987 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6988 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6989 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6990 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6991 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6992 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6993 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd
6994 ? Ss 0:00 /var/packages/FileStation/target/sbin/thumbd

You cannot disable or turn off the FileStation functionality without breaking some core GUI items that are required for normal functioning in the web interface. But, you can stop the thumbd service from running and chewing up unnecessary system resources. Here’s how:

  1. Browse to the /var/packages/FileStation/target/etc/conf directory.
  2. Issue this command to rename the thumbd.conf file:   mv thumbd.conf thumbd.conf.orig
  3. Reboot the Synology device.
  4. SSH into the device and you should no longer see any instance of the thumbd

  1. Thank you for posting this! I have a Synology DS212j Diskstation unit which has several instances of these thumbnail generator daemonised processes, but the Diskstation GUI offers no way to disable them or the generation of thumbnails.
