Disable Synology Thumbnails Generation

6 05 2014

Thumbnails generation on the Synology NAS can be a useless waste of resources, making your CPU run at 100% for hours or days. This behavior takes place whenever you upload any images without using the proper software released by Synology (i.e. Photo Station Uploader), for example when you upload your holiday pictures through SMB straight onto the Synology shared folder.
Please note that thumbnails are generated even though the Synology Photo Station software is disabled.

In order to avoid this behaviour, you should disable the service responsible for the thumbnails creation, that is /usr/syno/etc/rc.d/S77synomkthumbd.sh.

You can stop it: /usr/syno/etc/rc.d/S77synomkthumbd.sh stop but unless you want it up and running again after any reboot, you can disable it from executing:
chmod -x /usr/syno/etc/rc.d/S77synomkthumbd.sh

Please note that there are many others services running, most of which can be useless to you. Some of them are listed below.

EXACTLY what I’ve been looking for… when I try the chmod command though I get “Operation not permitted”… thoughts?
