Hello,

My Home Assistant OS vDisk is starting to get full and I'd like to increase it's size. However when I got to do so it does not save my changes and just snaps it back to what it was sized at before:

 

 

Click enter or off the text box and poof back to 32G:

 

I also tried qemu-img resize but it does not like my disk file:

 

root@HaynesTower:~# qemu-img resize "/mnt/user/domains/Home Assistant/haos_ova-10.5.vmdk" +96G

qemu-img: Image format driver does not support resize

 

I tried qemu-img convert as well which looked like it worked, it hung a while and then completed with nothing output, but the disk size remained the same.

 

Anyone overcome something like this?

Thanks!

I ended up creating a new vDisk and then moving the data disk within Home Assistant to it. So far so good but still curious why this functionality didn't work in unRAID.

Resize command of qemu-img doesn't work on vmdk files; you need to convert vmdk to qcow2 or raw with qemu-img convert command, then resize it.

To anyone who want to do this having VMDK image.

1. Make backup of you VM - just in case
2. Shutdown your VM
3. Convert VMDK to qcow2 

   qemu-img convert -p -f vmdk -O qcow2 /mnt/user/domains/home_assistant/haos_ova-6.0.vmdk /mnt/user/domains/home_assistant/haos_ova-6.0.qcow2

    

4. Change the path to your new disk in your VM
5. Change the type from raw to qcow2 in your VM

   <driver name='qemu' type='qcow2' cache='writeback'/>
         <source file='/mnt/user/domains/home_assistant/haos_ova-6.0.qcow2' index='1'/>

    

6. Update the setup, click on the VM and increase the disk size in UNRAID UI
