Hi, when i creating optimized versions of my files i get this error
[Req#9eb] TranscodeJobManager: [Running] directory is not writable: “/media/filme/_Filename_/Plex Versions/Optimized for Mobile”
My Server runs on Ubuntu Linux. My files comes via smb from my synology nas.
The folders are mapped with fstab.
192.168.178.100/movies /media/movies cifs credentials=/home/plex/.smbcredentials,iocharset=utf8 0 0
The “.smbcredentials” contains my synology username and password for the shares
The strange one, i can play and delete files without any issues.
Can anyone help me? Thanks in advance
Edit:
192.168.178.100/movies /media/movies cifs credentials=/home/plex/.smbcredentials,uid=ubuntu-username,iocharset=utf8 0 0
**uid=ubuntu-username,**
did the trick
