Umbrel freezes syncing

So a few hours ago i installed umbrel on my server (in a VM). I allocated 800GB SSD stoarge to it, but now in the umbrel GUI only 105.1GB shows up (I just noticed that), it was already like 98GB (around 15% i guess) but now it begins freezing and im stuck on this screen. anyone any idea, thank you so much!

Note: if i run sudo lshw -class disk it correctly shows the 800gb.

Update: if i do df -h it says this, so the file system isnt the whole disk or somthing anyone knows how to fix this?
