Help diagnosing why rootfs keeps filling up to 100% in the last few weeks

[tmchow]

Never before have I had this problem where my rootfs was filling up to 100%.  A few weeks ago, I was getting all sorts of error in Plex saying the disk was full, and when I tried to login to the unraid dashboard, it kept reloading and timing out. 

 

I then went to my phsyical machine and logged in, and at the terminal ran a "df -H /" and it showed rootfs was at 100% full.

 

I couldn't do anything and some research showed I should reboot which I did. That solved the problem.

 

However, since then, this has happened again a few days later so I'm trying to track down what's going on. I'm not aware of anything really changing my unraid setup other than container upgrades.  For example, I haven't suddenly changed where plex is doing it's transcodes but it's possible that it's filling up since 3-4 weeks ago I started upgrading movies to 4k counterparts from 1080p so the transcodes would be more aggressive.

 

However, I didn't know if that's it and don't know how to read my system diagnostics. I've attached them in hopes someone can help!

Where are you transcoding to?  Plex is terrible at deleting the multiple files it places in there until after playback is finished.

Transcoding to /tmp.  My system has 64GB of RAM.

Did you set a maximum Ram size so it doesn't blow up your RAM? Kinda like this?
