 ## Prereq
 
 1. Have a reverse proxy pointing at your server
 2. Have a valid certificate
 
+### Iscsi
+
+We can use iscsi to give nextcloud a large block store.
+
+On Nextcloud:
+
+1. Create an iscsi initiator in Truenas named `iqn.2024-02.com.reeselink:nextcloud-aio`.
+2. Create a new authorized access with username `iqn.2024-02.com.reeselink:nextcloud-aio` and password.
+3. Create a new target called `iqn.2024-02.com.reeselink:nextcloud-aio-data`
+   1. Create an alias called `Nextcloud AIO Data`
+   2. Select the exposed portal
+   3. Select the `iqn.2024-02.com.reeselink:nextcloud-aio` initiator group
+   4. Select CHAP Auth method
+   5. Select auth group containing `iqn.2024-02.com.reeselink:nextcloud-aio`
+4. Create a new extent called `nextcloud-aio-data`, leave all settings alone
+5. Create a new associated target with `iqn.2024-02.com.reeselink:nextcloud-aio-data` target and
+   `nextcloud-aio-data` extent
+
+On Nextcloud AIO:
+
+Edit `/etc/iscsi/initiatorname.iscsi` and set your initiatorname.
+
+Edit `/etc/iscsi/iscsid.conf`
+
+```conf
+node.session.auth.username = iqn.2024-02.com.reeselink:nextcloud-aio
+node.session.auth.password = <password>
+```
+
+```bash
+iscsiadm -m discovery -t st -p driveripper.reeselink.com
+iscsiadm -m node --login
+```
+
 ## Setup
 
+### IPV6 (Optional)
+
