Server version: 1.7.2.3878
OS: unRAID 6.3.5
I need help, I cannot seem to figure out what is happening. Plex becomes unresponsive frequently throughout the day. I see HIGH spikes of disk read. Here is a screenshot. http://imgur.com/a/1mvnr It happens enough to cause a disruption from my users and my wife messaging me that her playback gets interrupted. I am positive it is Plex, whenever it happens I shut down the plex docker and the disk activity goes away instantly. I have auto update library disabled. Scheduled tasks are set to run only between 10pm and 6am. Downloads only happen between 10pm and 6am as well. The server is pretty much not doing ANYTHING except handling plex playback during the day. I attached a link to my log files. It just happened this morning around 11:00-11:07
Sorry, these logs are quite useless because they cover only a few minutes each.
Please disable ‘verbose’ logging. Then restart the server.
If you press ‘Analyze’ on a single item, it gets its video preview thumbnails and the ‘extensive’ media analysis made instantly. Which involves reading the whole file from beginning to end.
(These things are otherwise performed during the ‘maintenance time’.)
It could be also Sync-Jobs.

This is frustrating because the last time I uploaded logs someone said that I had to enable Verbose for this stuff to be seen. Here are more logs .
Also, the drive that has the high read speed is not where my media is stored, it is where the application data is stored. I also have video previews/thumbnails disabled.

Your logs are still ‘verbose’ (I think you missed to restart Plex server )
but I think I know what is going on anyway:
the last 2 versions of PMS have a bug where the transcoder doesn’t ‘throttle’ itself after it has buffered a few minutes worth of transcoded video. Instead, it keeps on going until the whole movie has been pretranscoded.
This may be too much traffic for the disk, particularly if there are several transcodings are going on at the same time.
This is a known bug and it will get squashed shortly.
