How to find other drives on Linux?

[34626]

Is Jellyfin running in docker?
What Linux distro?
What filesystem is the drive using? If NTFS, i would recommend you, to move data away and format the drive into ext4

You can use "sudo fdisk -l" to see drives informations like /dev/sdb etc.
You need to create a folder for the mount like:
"sudo mkdir /mnt/ext1"
then to mount a drive to that path:
"sudo mount /dev/sdb /mnt/ext1/"

For permissions of the drive, you can use:
"sudo chmod -R 777 username:group /mnt/ext1/"
-R will change permission on all files and folders on the drive.
777 = all permissions
username is the name of the user and group should be the same.
/mnt/ext1/ is the path
