I am all of a sudden getting an error for dvr recordings “There was not enough free disk space to start the recording” but I have plenty of disk space on mu usb thumb drive.

here is what I find in the log

Why do you doubt this log entry? But take a look at df -h.

here is the df -h result

Ah. Now I know why you are confused :smiley: You think that you have mounted some other drive at /home/pi/usbstick/. However, at the moment there is only your SD card. That’s why /home/pi/usbstick/ also only points to data on your SD card. There is only 3.5 GB left on your SD card. That’s what Plex is telling you.

You can check your current mounts with mount.

The USB stick is not mounted at the moment so it cannot be used. Here is a great tutorial how to correctly setup your /etc/fstab configuration to mount your USB stick at boot. It’s most intended for mounting media, just adapt the mount points to your use case.

Thanks I have now mounted it as /disk/DVR but when I try to record I get “No write access to destination”

I tried sudo chown -R pi:pi /disk and got “Operation not permitted”

this si what I added to fstab

Mount USB stick for DVR

UUID=BCA7-632D /disk/DVR vfat defaults,auto,nofail 0 1

I appreciate all your help as you can tell I have n o idea what I am doing.

PMS runs as user plex, not pi. But this does not matter, as your vfat USB pendrive does not support permissions at all. If you plan to use this drive only with your RPi for now, you should consider to format this drive as ext4. But for now, just change the mount options in /etc/fstab slightly:

UUID=BCA7-632D /disk/DVR vfat defaults,auto,nofail,umask=000 0 1

It’s best to reboot your Pi afterwards. And please do not use chown for this mount point. It would only change the permissions temporarily till next reboot --> vfat does not store permissions.

That worked. Thank you for your help. I sure have a lot to learn.
