Trouble moving userdata

Troubleshooting
1

Complete noob at this so be gentle. Just got my Pi 3 and really fascinated by it so far.

I will try to explain what is happening as best as I can…

I have been trying to get DietPi and Plex setup this weekend (with attached USB HDD).

1.DietPi tells me that my userdata is here: User Data Location [Custom | /mnt/Plex/dietpi_user

2.When i try to transfer userdata i get : ERROR: source directory /mnt/Plex/dietpi_userdata does not exist.

  1. When i try to install Plex for DietPi i get : Error: DietPi-Userdata validation
    DietPi was unable to verify the existence of the userdata directory (/mnt/Plex/dietpi_userdata).

I think this got started because I had everything installed once and ran into some problems, then tried to back everything out and then do it again, so I know that I have screwed up something somewhere.

If someone could help me out, I would appreciate it.

Like I said, completely new at this so if there is a solution, dumb it down for me as much as possible,LOL. It may be obvious to you but it will not be for me probably.

Thanks!

I am assuming the following:

  1. You used dietpi-drive_manager to mount your usb drive and you told it to mount the drive on /mnt/Plex
  2. In dietpi-drive_manager you clicked the selection to put the dietpi user directory in /mnt/Plex.

what is the output of

  1. ls -lah /mnt/
  2. cat /etc/fstab


    Also could you have a capitalisation issue? remember in linux /mnt/Plex is different than /mnt/plex

Hi,

Thanks for the help. I sent a reply to your questions last night, but don’t see it in the thread for some reason. I’ll try again.

So it looks like your dietpi installation believes that the user data is stored in /mnt/Plex/dietpi_userdata

dietpi_userdata → /mnt/Plex/dietpi_userdata>>

However it looks like your external disk is mounted as /mnt/Dietpi
UUID=DA18EBFA09C1B27D /mnt/DietPi auto defaults,noatime,rw,nofail,x-systemd.automount,permissions 0 0

I would go into dietpi drive manager and select the / disk.
then move the userdata back to your / partition
then using drive-manager correct the mountpoint for your external disk.

the command df should show you were your disks are mounted.

You can also edit /etc/fstab and change
UUID=DA18EBFA09C1B27D /mnt/DietPi auto defaults,noatime,rw,nofail,x-systemd.automount,permissions 0 0
to
UUID=DA18EBFA09C1B27D /mnt/Plex/ auto defaults,noatime,rw,nofail,x-systemd.automount,permissions 0 0

Then

umount /mnt/Dietpi
mount /mnt/Plex

Then you can go back to drive manager and move your user data to /mnt/Plex/
