Vhdx partition size

Hello all

Sorry for the stupid questions, I always forget the thing with linux disc layouts.
When I list the filesystems, it returns:
When I list the block devices, I get:
As far as I understand, sda8 is only using 5.3GB of the whole 20GB vhdx image. This seems to be the reason HA displays in the system monitor 80% disk utilisation.

Why do I see 100% on /dev/root?
Can I simply run resize2fs to extend sda8, or will this crash the other partitions?
And if so, why is sda8 not using the whole space in the vhdx image by default?

Cheers, Lukas

Hi Lukas,

Did you follow the procedure here? https://community.home-assistant.io/t/hass-io-on-hyper-v-step-by-step/140553

Indeed, I did.
But when I update to a newer version, my disk gets full. See:

and the update fails:
19-11-02 14:34:59 CRITICAL (MainThread) [hassio.homeassistant] HomeAssistant update fails -> rollback!

Plus, as far as I know, one wouldn’t use the opt nobarrier, see: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/storage_administration_guide/writebarrieronoff

So, default behaviour is, sda8 would increase automatically, right?
Anyways, manual work did the trick.
