Cannot create PV on openshift standalone 4.12

Hello everyone, i have installed OpenShift standalone 4.12 on a bare metal server.

When i try to create a PVC for a git task, the PV isn't created and the pod gives this error:
" 0/1 nodes are available: 1 node(s) did not have enough free storage."
The default storage class is topolvm, and the topolvm-node pod is stuck at init:0/1.

Any help would be appreciated, Thank you.
