Pxc-db cluster unable to recover after crash

Hi @sanch1709
it looks like the container pxc isn’t running, that is why you get

error: unable to upgrade connection: container not found ("pxc)

You are correct that the cluster being unhealthy will not let the statefulset continue deployment of nodes pxc-1 and pxc-2. They will not be created until pod pxc-0 is in a healthy state. pxc-0 has only 2/3 containers running, it is probably container pxc that isn’t running
You can check the logs on the container:
kubectl logs pod pxc-0 -c pxc
And you could check the logs from the operator:
kubectl logs pod percona-xtradb-cluster-operator-*-*
