Hi,
I’ ve been looking for the same answer.
Update at the end
My setup is:
HASSOS on PROXMOX, network share and Frigate
- Home Assistant 2023.5.3
- Supervisor 2023.04.1
- Operating System 10.1
- Frontend 20230503.3 - latest
running under pve in container (size:32GB) and the fileserver (Debian GNU/Linux 11 (bullseye)) in lxc with Cockpit. The shared dirs everywhere else are working (smb and nfs with full access and Timemachine also)
I have Cams, and Frigate add-on installed (not supporting volume settings).
- (Full Access)
- Current version: 0.12.0
The recordings and clips should not to be saved to HAOS container.
What i tried
mount -t nfs4 -o rw 192.168.1.234:/media/dockervolumes/frigate /media/frigate
result allways the followings:
Read-only and didn’t mount it
mount: /media/frigate: cannot mount 192.168.1.234:/media/dockervolumes/frigate read-only.
dmesg(1) may have more information after failed mount system call.
Now google is my friend, and searched the web and found the followings:
After the research 
AFAK, the OS is running in a docker container on the host. Changes aren’t visible to other add-ons and not permanent. → if succesed
Q:
This is the only way to mount nfs share, mentioned in this post: Mounting NAS Shares for Frigate in Home Assistant OS or exists a more UserFriiendly method?
Help would be appritiated
Update:
Reading the [SOLVED] HASSOS mount NAS network share topic first post and than this one
