Our Storage backbone had some problems during this, one of the nodes lost his

How can I bring back the host into the Cluster without rebooting?
Was the cluster network on the storage backbone (I assume you mean
network here)?
If not, the loss could be the result of heavy load on the node resulting
from the outage.
Else this would be weird, as quorum does not depend directly on the
running (or failed) VMs.
I'd check if the problematic Node can send to the other nodes via
multicast [1]
then restarting corosync and eventually pve-cluster should do it:
systemctl restart corosync pve-cluster
cheers,
