ssd full

I'm having a situation. My 256gb nvme ssd is full of memory when I create 5 vms. And let me ask, in vms I have emptied the trash and unused files but the memory of the ssd has not decreased.

Long story short: ssd is full, can boot server w some errors on boot, can login root, but can not run any qm commands even qm list - i/o error what to do? If I add some drive does it help? How to add drive without web interface? May I just move VMs manually to new hdd, format and setup...
