 Having a mesh network on our hosts is great for securing all the traffic between them for our future k3s setup. A self-managed WireGuard mesh network is better than Tailscale as it eliminates reliance on a third party and provides full control over the configuration. It reduces unnecessary abstraction and "magic," enabling easier debugging and ensuring full ownership of our network.
 
-I look forward to the next blog post in this series. We may start setting up k3s or take a first look at the NFS server (for persistent storage) side of things. I hope you liked all the posts so far in this series.

+## Introduction
+
+In the previous posts, we set up a FreeBSD-based Kubernetes cluster using k3s. While the base system works well, Kubernetes workloads often require persistent storage for databases, configuration files, and application data. Local storage on each node has significant limitations:
+
+* No data sharing: Pods (once we run Kubernetes) on different nodes can't access the same data
+* Pod mobility: If a pod moves to another node, it loses access to its data
+* No redundancy: Hardware failure means data loss
+
+This post implements a robust storage solution using:
+
+* CARP: For high availability with automatic IP failover
+* NFS over stunnel: For secure, encrypted network storage
+* ZFS: For data integrity, encryption, and efficient snapshots
+* `zrepl`: For continuous ZFS replication between nodes
+
+The result is a highly available, encrypted storage system that survives node failures while providing shared storage to all Kubernetes pods.
+
+Other than what was mentioned in the first post of this blog series, we aren't using HAST, but `zrepl` for data replication. Read more about it later in this blog post.
+
+## Additional storage capacity
+
+We add 1 TB of additional storage to each of the nodes (`f0`, `f1`, `f2`) in the form of an SSD drive. The Beelink mini PCs have enough space in the chassis for the extra space.
+
+[![./f3s-kubernetes-with-freebsd-part-6/drives.jpg](./f3s-kubernetes-with-freebsd-part-6/drives.jpg)](./f3s-kubernetes-with-freebsd-part-6/drives.jpg)  
+
+Upgrading the storage was as easy as unscrewing, plugging the drive in, and then screwing it back together again. The procedure was uneventful! We're using two different SSD models (Samsung 870 EVO and Crucial BX500) to avoid simultaneous failures from the same manufacturing batch.
+
+We then create the `zdata` ZFS pool on all three nodes:
+
+```sh
+paul@f0:~ % doas zpool create -m /data zdata /dev/ada1
+paul@f0:~ % zpool list
+NAME    SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
+zdata   928G  12.1M   928G        -         -     0%     0%  1.00x    ONLINE  -
+zroot   472G  29.0G   443G        -         -     0%     6%  1.00x    ONLINE  -
+
+paul@f0:/ % doas camcontrol devlist
+<512GB SSD D910R170>               at scbus0 target 0 lun 0 (pass0,ada0)
+<Samsung SSD 870 EVO 1TB SVT03B6Q>  at scbus1 target 0 lun 0 (pass1,ada1)
+paul@f0:/ %
+```
+
+To verify that we have a different SSD on the second node (the third node has the same drive as the first):
+
+```sh
+paul@f1:/ % doas camcontrol devlist
+<512GB SSD D910R170>               at scbus0 target 0 lun 0 (pass0,ada0)
+<CT1000BX500SSD1 M6CR072>          at scbus1 target 0 lun 0 (pass1,ada1)
+```
+
+## ZFS encryption keys
+
+ZFS native encryption requires encryption keys to unlock datasets. We need a secure method to store these keys that balances security with operational needs:
+
+* Security: Keys must not be stored on the same disks they encrypt
+* Availability: Keys must be available at boot for automatic mounting
+* Portability: Keys should be easily moved between systems for recovery
+
+Using USB flash drives as hardware key storage provides a convenient and elegant solution. The encrypted data is unreadable without physical access to the USB key, protecting against disk theft or improper disposal. In production environments, you may use enterprise key management systems; however, for a home lab, USB keys offer good security with minimal complexity.
+
+### UFS on USB keys
+
+We'll format the USB drives with UFS (Unix File System) rather than ZFS for simplicity. There is no need to use ZFS.
+
+Let's see the USB keys:
+
+[![USB keys](./f3s-kubernetes-with-freebsd-part-6/usbkeys1.jpg "USB keys")](./f3s-kubernetes-with-freebsd-part-6/usbkeys1.jpg)  
+
+To verify that the USB key (flash disk) is there:
+
+```
+paul@f0:/ % doas camcontrol devlist
+<512GB SSD D910R170>               at scbus0 target 0 lun 0 (pass0,ada0)
+<Samsung SSD 870 EVO 1TB SVT03B6Q>  at scbus1 target 0 lun 0 (pass1,ada1)
+<Generic Flash Disk 8.07>          at scbus2 target 0 lun 0 (da0,pass2)
+paul@f0:/ %
+```
+
+Let's create the UFS file system and mount it (done on all three nodes `f0`, `f1` and `f2`):
+
