Permission denied from root within LXC to mergerfs storage

[Jonathan137]

Situation
Within LXC 100 being user 1000 I can read and write to both /mnt/storage as /mnt/music
Being the root within the LXC I can read and write to /mnt/music but only read to /mnt/storage
If I make a folder with 777 as permission, I can write as root in that folder showing the owner root:root
Being on proxmox level self I can write as root to /mnt/storage.

Who knows what goes wrong or what is missing?



My configuration:
mergerfs v2.40.1
