HaOS - Home Assistant OS - "Not enough space on drive" - Not core

Insight & Feedback

I am trying to install the Home Assistant full OS (HaOS) using the haos_generic-x86-64-16.2.img

I prefer HaOS over the Docker version, as I like to have everything related to Home Assistant in our VM, and the updating of the add-os is also easier and so is the backup as i have everything in one.

I have installed this many times over the year on different device without issues and for the last year it ran on my Proxmox cluster.

But when i try to install it on ZimaOS as a ZVM, it seems to run the installer just fine, netkort is mapped correct and it pulls and IP from my DHCP. I can access the webinterface, but it never completes the installer, as it says it is out of diskspace. I have assigned 32GB from my SSD pool, so there should be enough.

Any cluse ?

My assumption would be that it doesnt see the harddrive correct, but that seems odd, as I havent had that issue on other virtualization platforms…

Hi, did you find a solution?

I believe this is related to how the virtual disk is initially presented to the guest OS during installation.

HAOS expands its partitions very early in the install process. With smaller virtual disks (for example 32 GB), the installer may only detect the base image size and report insufficient space, even though more storage is allocated.

I suggest:

  • Creating the VM with 64 GB or larger disk
  • Using BIOS firmware instead of UEFI
  • Recreating the VM after applying these settings

Once installed, HAOS runs normally and uses the full disk space as expected.

Exactly as gelbuilding replied.

It is part of how the read-only filesystem sees/looks from the user’s point of view.

I did a reinstallation (a different reason) and it was the same straight away, so normal :slightly_smiling_face:
