L0rdRaiden Posted March 6, 2022 Share Posted March 6, 2022 (edited) I am getting this errors every 10-15 days or so Mar 6 04:30:05 Unraid root: Fix Common Problems: Error: Invalid folder cache contained within /mnt Mar 6 04:30:08 Unraid root: Fix Common Problems: Error: Out Of Memory errors detected on your server Other related settings Disk Cache 'vm.dirty_background_ratio' (%): 2 Disk Cache 'vm.dirty_ratio' (%): 3 Any Idea how to fix it?

itimpi Posted March 6, 2022 Share Posted March 6, 2022 You are likely to get better informed feedback if you post your systems diagnostics zip file as without those we are just guessing. The messages suggest you have something mapped to /mnt/cache (probably a docker container) and you do not have a pool called 'cache'. This would mean that the /mnt/cache location is in RAM so writing to this that will fill up your RAM. Quote Link to comment

It might be that I have plex transcode on RAM bust last time plex was used, was like 10 hours before that out of memory error happened.

itimpi Posted March 6, 2022 Share Posted March 6, 2022 Your original post mentioned getting: Mar 6 04:30:05 Unraid root: Fix Common Problems: Error: Invalid folder cache contained within /mnt which was my big concern. If this repeats then it is almost certainly a misconfigured docker container referencing that path. I do not see this repeated recently so you might want to run Fix Common Problems again to see if that path still exists and if it does look at what that path contains to give you a clue as to what creates it.

Squid Posted March 6, 2022 Share Posted March 6, 2022 Additionally, you do NOT want to use a host path of /tmp for Plex's transcoding Use /tmp/Plex instead Without the subfolder, Plex *may* wind up deleting files at any given point in /tmp which will adversely affect the OS 1 Quote Link to comment

I have re run fix common problems and still appears, I think is because this "Remote" folder that I think I created when I had rclone. But now I can't delete it. And regarding the out of memory errors could be related with this settings? what are the recommended values if I have 32 GB of ram and usually half of it is no being used.

L0rdRaiden Posted March 6, 2022 Author Share Posted March 6, 2022 Regarding OOM errors I am going to follow this advice and see how it goes Quote Link to comment

Look first at any docker apps (hit show more settings) for something that has a path mapping directly referencing /mnt/cache Fix that and reboot and then see what FCP says again Quote Link to comment
