=Proxmox=<br />
===Lets create the SSH keys on the proxmox boxes. (The IP must match your iSCSI Portal IP)===<br />
You only need to create the keys on one node if they are clustered as the keys will replicate to the other nodes.<br />
<br />
*portal_ip=192.168.1.1<br />
*mkdir /etc/pve/priv/zfs<br />
*ssh-keygen -f /etc/pve/priv/zfs/$portal_ip_id_rsa<br />
*ssh-copy-id -i /etc/pve/priv/zfs/$portal_ip_id_rsa.pub root@$portal_ip<br />
<br />
===Enable "Log in as root with password" under Services -> SSH on the FreeNAS box.===<br />
<br />
===Make an SSH connection from every node to the iSCSI Portal IP===<br />
<br />
*ssh -i /etc/pve/priv/zfs/$portal_ip_id_rsa root@$portal_ip<br />
<br />
===Install the REST client on every node===<br />
<br />
*apt-get install librest-client-perl git<br />
<br />
===Download the patches on every proxmox node===<br />
<br />
*git clone https://github.com/TheGrandWazoo/freenas-proxmox<br />
<br />
===Install the patches on every proxmox node===<br />
<br />
*cd freenas-proxmox<br />
*patch -b /usr/share/pve-manager/js/pvemanagerlib.js < pve-manager/js/pvemanagerlib.js.patch<br />
*patch -b /usr/share/perl5/PVE/Storage/ZFSPlugin.pm < perl5/PVE/Storage/ZFSPlugin.pm.patch<br />
*patch -b /usr/share/pve-docs/api-viewer/apidoc.js < pve-docs/api-viewer/apidoc.js.patch<br />
*cp perl5/PVE/Storage/LunCmd/FreeNAS.pm /usr/share/perl5/PVE/Storage/LunCmd/FreeNAS.pm<br />
<br />
===Restart the PVE services===<br />
<br />
*systemctl restart pvedaemon<br />
*systemctl restart pveproxy<br />
*systemctl restart pvestatd<br />
<br />
If you are using a cluster restart the following services as well.<br />
<br />
*systemctl restart pve-ha-lrm<br />
*systemctl restart pve-ha-crm<br />
<br />
Reload the PVE webgui. Now FreeNAS-API should we available as a iSCSI provider.<br />
<br />
===Create a iSCSI target on the FreeNAS box.===<br />
You dont need to create any extents as the FreeNAS-API plugin will do this automatically when the drive is created on the VM.<br />
<br />
NOTE: If you followed this guide you already created your target<br />
<br />
===Setup ZFS Over iSCSI i Proxmox GUI. choose FreeNAS-API as provider.===<br />
<pre><br />
ID: Whatever you want<br />
Portal: iSCSI portal IP on the freenas box<br />
Pool: Select your pool (eg: dagobert/VirtualMachines )<br />
ZFS Block Size: 4k<br />
Target: IQN on the FreeNAS box and target ID (eg: "qn.2005-10.org.freenas.ctl:iscuzzy")<br />
API use SSL: Unchecked<br />
API Username: root<br />
API IPv4 Host: iSCSI portal IP on the freenas box<br />
API Password: root password on freenas box<br />
Thin provision and Write cache is optional<br />
</pre><br />

<br />
==API after update==<br />
Note: A pve-manager upgrade will replace the patched files so i suggest you create a bash script<br />
and run it on every node after an upgrade.<br />
<br />
I have a script that looks like this<br />
<br />
<pre><br />
#!/bin/bash<br />
<br />
cd /root/freenas-proxmox <br />
<br />
patch -b /usr/share/pve-manager/js/pvemanagerlib.js < pve-manager/js/pvemanagerlib.js.patch<br />
patch -b /usr/share/perl5/PVE/Storage/ZFSPlugin.pm < perl5/PVE/Storage/ZFSPlugin.pm.patch<br />
patch -b /usr/share/pve-docs/api-viewer/apidoc.js < pve-docs/api-viewer/apidoc.js.patch<br />
<br />
cp perl5/PVE/Storage/LunCmd/FreeNAS.pm /usr/share/perl5/PVE/Storage/LunCmd/FreeNAS.pm<br />
<br />
systemctl restart pvedaemon<br />
systemctl restart pveproxy<br />
systemctl restart pvestatd<br />
<br />
systemctl restart pve-ha-lrm<br />
systemctl restart pve-ha-crm <br />
