Ok, I messed up.
I followed a guide how to install FileBrowser and I set User ID to root for easy access and to play around, yes yes Im stupid.
I got all up and running and once completed “Move” migration of a few folders between dataset Media → Data, Truenas dashboard indicated that Data was still empty.
I log in via SMB and folder is also empty. I go back to FileBrowser where i can see the files in Data folder…
Logging in as root and check via Shell, /mnt/volume_03/Data folder and it is still empty…
Any ideas to solve this? the files are there but how to retrieve them
