Is there any FREE software out there that will allow you to creat a storage array and have two nodes that are active/active or active/passive? Similar to an enterprise array, so if one node fails the other will take over.

You can do DRBD between hosts and effectively RAID 1 mirror a block device from one to the other. Using that, an NFS server and some cluster software on linux like corosync/pacemaker you can automate failover from active to standby nodes and promote services on the other node and flip ip addresses etc.
It's an acronym that stands for Distributed Replicated Block Device. It's a linux project that effectively does RAID 1 via network from one machine to another. Too complicated to explain in a single post but if you know linux and want to expand into clustering then I recommend https://www.alteeve.com/w/AN!Cluster_Tutorial_2 as a good starting point.
When using Proxmox I assume that I will need to have a vm like TruNAS to serve NAS, iscsi and FC connectivity to the storage?
Not necessarily. You can set up CephFS on top of a Ceph pool. To what extent you can then directly share that via the GUI, I don't know—I never explored that any further. Under the hood, Proxmox is Debian, and the packages can be installed manually. But yes, a TrueNAS VM hosted on Ceph would indeed be HA-redundant; with three nodes, you can afford to lose one.
