Hello folks,
my NAS (TS-230, QTS 5.2.5.3145) has many thumbnail (195145 exactly) and it is a pity to use the gui for Multimedia console… I want to switch off the thumbnail generation, is it possible to do this via ssh ?
Hi @vege44 I had a quick look at this.
If you edit /share/CACHEDEV1_DATA/.system/idbserver.conf (depending on your actual volume name), then find the myidbserver config block, then change the value of ENABLE to false, this then shows in the MMC web UI as thumbnail generation disabled (it’s not a live change, so reload the MMC UI).
Note: this key-value pair is most-likely changed after the thumbnail service has been enabled/disabled so it’s doubtful it will actually stop any thumbnails being generated. It won’t trigger the daemon that generates thumbnails to behave any differently in your current QTS session, but would most likely apply when the service is next restarted.
However, I hope this has at-least been some help. It seems the thumbnail generator is called ‘idbserver’, so that’s probably what you’d need to look-for in the way of processes or configs. That’s where I’d concentrate my efforts.

Actually, you might be able to get the result you need by stopping the current MMC service, changing that value, then restarting MMC:
/etc/init.d/MultimediaConsole.sh stop
setcfg myidbserver ENABLE false -f $(getcfg SHARE_DEF defVolMP -f /etc/config/def_share.info)/.system/idbserver.conf
/etc/init.d/MultimediaConsole.sh start
This should make MMC reload the config files and apply their settings.
Hello @vege44 ,
Thank you reaching out to the community and we would be happy to help you with your problem.
We’d like to better understand your concern. Could you kindly clarify what you meant by “it is a pity to use the GUI for Multimedia Console”? Are you experiencing any issues with the current graphical interface, or would you prefer to have non-GUI (e.g., command-line) options to disable thumbnail generation?
Your input is valuable to us, and we want to ensure we address your needs appropriately.

Thank you and Looking forward to your response.
Hello OneCD,
thank you very much for your solution, it works fine !
But now, I think I have a new problem, my NAS “scratch” for two days (disk activity will be the exact term). I was thinking this was the consequence of thumbnail generation, but it seem this is not the case, the thumbnail generation is now off, as the indexation… I do not understand what is the reason :-/
I say “it is a pity…” because when I try to switch off thumbnail generation, the gui interface stay working and I can not use the button to switch off…
Dear @vege44
Thank you for the clarification. I just tried the GUI interface to disable the Thumbnails generation and it worked very smoothly. PFA the screenshot.
Having said that, I am afraid your NAS may have some issue and we would like to review the same and help to fix. request you to kindly raise a Support ticket so that our tech support team can review the logs and try to fix the problem.

Thank you.
Hello Amol, I have sumit a ticket… It appear firstly that stopping Multimedia Console is not possible unless uninstall it… So the option “Arêter” (stop) under AppCenter for Multimedia Console is a joke ?! I think it is time for me to think about a new NAS…
Thank you for submitting the support ticket, our tech support staff shall work closely with you to solve the issue as soon as possible. Could you please share the ticket number so that I may monitor it as well, thank you.
