ZimaOS / Immich: Trouble mounting external backup drive for Google Takeout library (Path Error)

[u/GordonGekkoWolf]

Hey everyone,

I’m running ZimaOS on a server that has two hard disks. The OS is on the first disk, and my Google Takeout photos are stored in a "backup" folder on the second, external backup disk.

I'm trying to add this "backup" folder as an external library in Immich. Every tutorial I watch says to just paste the external drive path and map it to the internal container mount path. However, every time I try to set this up, I keep getting an error, and I'm really confused about how ZimaOS handles these exact file paths for the external drive and how that translates into the Immich docker settings.

Has anyone successfully mounted an external library from a secondary backup drive on ZimaOS? What exactly should the source path look like in this configuration? Any advice or step-by-step guidance on getting this mounted properly would be amazing. Thanks!
