Emby filling Synology NAS drive within minutes?

[CrushWineBar 1]

I'm running the Emby server on a Synology DS220+ with dual Samsung 860 EVO 500GB drives, 10GB RAM and Celeron J4025 CPU.  On the drive that I use for Emby, I have about 125GB of video files.  I play these videos on 5 LG smart TVs.

When the videos play, the drive fills up quickly.  For example, this morning, I checked the volume, it was at 26% capacity.  Then I started the video on all 5 tvs.  Within 30 minutes, the volume was at 93% capacity and the videos were dragging.

I am not a techie, so I have no idea why this would be happening.  Can anyone advise?  I am attaching most recent log.

Thanks in advance.

****After posting this, I turned the videos off.  Magically, volume is back at 26% capacity...

Thank you.

Hi, what you likely did is playback 5 things that did NOT direct play.  Meaning Emby had to transcode or convert the files on the fly to make them a format the LG could play.
When this happens Emby essentially is re-writing the file as it goes and using up disc space until the player is done with it.
In your case you had 5 of these going.

You mentioned you have two 500 GB drives or half a TB.  I imagine these are mirrored so you have roughly 1 475 MB drive.  Out of this drive is the Synology system partition with left over scraps for the volume.  Now you have your apps installed and Emby as well as 125GB of media files.
Emby of course will need some of this space to hold graphics and other info about your media.

So there isn't a lot of working space left at this point so now if your playback requires transcoding you get the idea, data storage shrinks fast.

Now if you had added a couple of 4TB or 8TB or 16TB drives which are what most people use these days things would be a lot different as you have a lot more storage on hand.  Instead of seeing a huge amount of additional storage in use it would have likely been less than 1% (percent to overall storage space).

You really want to think about getting some bigger drives in that NAS.

Thanks, Cayars.  I don't have the drives mirrored, so the drive Emby is on has 500GB of space and 125 GB of video files.  Emby has 375GB of room to play with.  However, based on what you are telling me, and my experience thus far, this clearly isn't enough space.  I'm picking up an 8GB drive tomorrow, we'll see how things go.

Thanks for the insight.

I would look in your transcode-temp folder and see if you have rouge transcode session files that have not been cleaned up.  But yes from a Live TV and file transcoding standpoint you may need a lot of space.

I think that's a great choice and look forward to hearing your results.  I just picked up a Synology myself and going through some of the same things.

Off topic but wondering based on your user name, do you press and make your own wines?

My focus would be why is the file transcoding ...

It is always better to invest time in fixing the source file vs trying to fix the transcoding 'problem'.

LG TV's should be able to pretty much play everything, even with the out of date client - the only time they should need to trancode, is if HD Audio/DTS is being used (on newer Gen TV's)

Do you have any ffmpeg logs to share ?

No, I've been in the wine business for 25 years, but I'm not a winemaker.  20 years in sales, all over the world, now my wife and I own a wine bar in Colorado (called Crush).

Also off topic - I like your avatar.  Alex is a friend.

Thanks, RBJ.  I don't have the slightest idea where to find ffmpeg logs.  If you can point me the right direction, I'll be happy to share.  Much appreciated.

Very cool on both counts. Total shame about Neil.
Not many people likely get the avatar reference, but it's from one of my favorite periods of theirs.

Did you meet Alex via Crush?

Yes, the world is worse without Neil in it.  Great musician, terrific human being.  Only met him twice, spent very little time with him, but he could not have been more kind.  I met Alex through a mutual friend, a guy I grew up with and remain close with to this day.  He went off and made a heap of money, got to know the band really well and introduced me to them.  I know Geddy (who is a MASSIVE wine geek) also, just haven't spent as much time with him as I have Alex.  I was lucky enough to be able to hang with them (until the friggin sun came up - not an easy thing for a bunch of old guys!!) after their final show in LA on the R40 tour.  Good times!

Since we are talking about Synology you can download them via Dashboard-Logs if you don't want to ssh to the log folder.
