 ### Setup
-**TODO**: Check if this is still annoying.
 
 1. Enable the `contrib` and `non-free` repo areas. (Don't use any backports repo.)
 1. Install (it might give errors): `zfs-dkms zfsutils-linux zfs-zed`
 1. Load the ZFS module: `modprobe zfs`
 1. Fix the ZFS install: `apt install`
+1. Make the import service wait for iSCSI:
+    1. `cp /lib/systemd/system/zfs-import-cache.zervice /etc/systemd/system`
+    1. Add `After=iscsi.service` in `/etc/systemd/system/zfs-import-cache.service`.
+    1. `systemctl enable zfs-import-cache.service`
 1. Set the max ARC size: `echo "options zfs zfs_arc_max=<bytes>" >> /etc/modprobe.d/zfs.conf`
-  - It should typically be around 15-25% of the physical RAM size on general nodes. It defaults to 50%.

 ### Troubleshooting
 
 - `zfs-import-cache.service` fails to import pools because disks are not found:
-  - Try setting `options scsi_mod scan=sync` in `/etc/modprobe.d/scsi.conf` (e.g.) to wait for disks to come online before ZFS starts.
