io-error on VM because disk is full

[Poikon]

Hello friends,
I get the io-error on a 2012r2 VM that has the following configuration:

The disk ssd-img is full:

The VM raw disk has size of 999.65GB

I only run this VM on this node, how can I fix this?
The VM cannot start, I get the yellow mark and cannot access the OS so to delete the large files

How would you fix this on a (physical) Windows machine when the disk was full and it does not boot anymore?

Maybe boot the VM with a GParted Live ISO and hope it can mount the virtual disk to delete files? Does Windows have rescue boot options. maybe?
Maybe add another Proxmox storage (remote NFS/SMB or physical drive) and create another Windows VM and use that to mount the existing drive to delete files?

I would restore a backup but you seem to have excluded the virtual disks. Since you don't seem to care about the data.I would delete the VM and make a new one (but not use thin storage).

I will try with GParted Live ISO and let you know.
Windows doesn't boot, it hangs on loading
I do care about the data, but I did a bad job setting up this VM

No need to get back to me personally.I know very little about rescuing Windows and your issue is not really related to Proxmox.

But you would be fine with losing it all when the drive breaks?! Next time, make a VM that is backed up (properly, 1-2-3 and all that) before putting important data on it.

EDIT: I do hope you setup discard/trim and installed VirtIO SCSI drivers inside the VM for the virtual disks. Otherwise deleting files might not even free up space...
