Emby download caused high disk usage leading to no access to DSM

[txapo 0]

Hey,

I just recently switched to Emby Premier and yesterday I tryed to download a TV show episode for the first time. Well, it didn't go well. It ended up with me not being able to access my NAS at all (nor my Emby server) due to high disk usage (both disk led lights are flashing green nonstop). I tryed rebooting my NAS but it didn't solve the issue. I am able to find the NAS both in my router interface and Synology Assistant, meaning LAN is fine.

Has anyone encountered this issue before? Is there anything I can do?

Thanks!

Ok, so I was just able to access my Emby Server and I was able to stop the "Convert media" process (only 0.7% completed in almost 24 hours), and that solved the issue. But why does a download trigger such a high disk usage?

Some reddit user suggested the following (I have a DS218play NAS):

Emby actually requires 2GB of ram and your NAS only has 1GB, I believe. You need to lower the RAM usage to an absolute minimum for it to not overwhelm the NAS.

Unfortunately you can’t install more RAM in your model.

 

Can any dev confirm it?

hi, the requirement really depends on your usage of the server, e.g. how many users, what features you use and enable. I would say 1GB could be fine for some but it is certainly pushing it. You may want to consider a ram upgrade if you can.

If it's converting then it means that the download has to be converted first before it is transferred. This could result in high disk usage because the entire file has to be read and and a new one created at the same time.

You can avoid this with a user permission by unchecking this for that user: "Allow media downloading that requires transcoding".

But the consequence is that the original file may not be playable on their device, or their device may not have enough space for it.
