+I have since replaced the 1TB drives with 4TB drives for more storage capacity. The upgrade procedure was different for each node:
+
+**Upgrading f1 (simpler approach):**
+
+Since f1 is the replication sink, the upgrade was straightforward:
+
+1. Physically replaced the 1TB drive with the 4TB drive
+2. Re-setup the drive as described earlier in this blog post
+3. Re-replicated all data from f0 to f1 via zrepl
+4. Reloaded the encryption keys as described in this blog post
+5. Set the mount point again for the encrypted dataset, explicitly as read-only (since f1 is the replication sink)
+
+**Upgrading f0 (using ZFS resilvering):**
+
+For f0, which is the primary storage node, I used ZFS resilvering to avoid data loss:
+
+1. Plugged the new 4TB drive into an external USB SSD drive reader
+2. Attached the 4TB drive to the zdata pool for resilvering
+3. Once resilvering completed, detached the 1TB drive from the zdata pool
+4. Shutdown f0 and physically replaced the internal drive
