pls help with write permissions on a NAS

[TheDreadPirate]

The NAS has no idea who the jellyfin user is. In your other thread you provided a username in the SMB's fstab.

Code:

//192.168.0.216/Public /media/Public cifs rw,relatime,vers=3.1.1,cache=strict,username=stooovie,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.216,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1 0 0

You have A LOT of extra parameters that are probably not needed, but the one we care about is "username=stooovie". All accesses that are made from your Proxmox server are sent to the NAS with that username. So "stooovie" is the user on the NAS that needs to have permissions to read and write. Your other option is to YOLO and make the share completely open (not recommended).
