Install FreeNAS Initiator When the cluster is used a convergent model with TrueNAS, the patches need to be installed for the FreeNAS Initiator to show under the storage dialogue GitHub Repo   Option 1 Connect to each node and install the following keys curl https://ksatechnologies.jfrog.io/artifactory/ksa-repo-gpg/ksatechnologies-release.gpg -o /etc/apt/trusted.gpg.d/ksatechnologies-release.gpg curl https://ksatechnologies.jfrog.io/artifactory/ksa-repo-gpg/ksatechnologies-repo.list -o /etc/apt/sources.list.d/ksatechnologies-repo.list Then issue the following to install the package Line 3 may now be in the code after I put in the GitHub issue. Link apt update apt install freenas-proxmox -y systemctl restart pvescheduler.service   Option 2 This is the manual way to do this. However, I don't do it this way now that there is a package to install. The benefit to the package is that once Proxmox is updated, the TrueNAS configurations are not overwritten.   Let's create the SSH keys on the Proxmox boxes. (The IP must match your iSCSI Portal IP) You only need to create the keys on one node if they are clustered as the keys will replicate to the other nodes. $portal_ip=192.168.2.252 mkdir /etc/pve/priv/zfs ssh-keygen -f /etc/pve/priv/zfs/$portal_ip_id_rsa ssh-copy-id -i /etc/pve/priv/zfs/$portal_ip_id_rsa.pub root@$portal_ip Enable "Log in as root with password" under Services -> SSH on the FreeNAS box. Make an SSH connection from every node to the iSCSI Portal IP ssh -i /etc/pve/priv/zfs/$portal_ip_id_rsa root@$portal_ip   Install the REST client on every node apt-get install librest-client-perl git   Download the patches on every Proxmox node git clone https://github.com/TheGrandWazoo/freenas-proxmox   Install the patches on every Proxmox node These can be run all at once but it is harder to see the output cd freenas-proxmox patch -b /usr/share/pve-manager/js/pvemanagerlib.js < pve-manager/js/pvemanagerlib.js.patch patch -b /usr/share/perl5/PVE/Storage/ZFSPlugin.pm < perl5/PVE/Storage/ZFSPlugin.pm.patch patch -b /usr/share/pve-docs/api-viewer/apidoc.js < pve-docs/api-viewer/apidoc.js.patch cp perl5/PVE/Storage/LunCmd/FreeNAS.pm /usr/share/perl5/PVE/Storage/LunCmd/FreeNAS.pm   Restart the PVE services systemctl restart pvedaemon systemctl restart pveproxy systemctl restart pvestatd If you are using a cluster restart the following services as well. systemctl restart pve-ha-lrm systemctl restart pve-ha-crm systemctl restart pvescheduler.service Reload the PVE webgui. Now FreeNAS-API should be available as an iSCSI provider.
