I am running a 4 disk raid 10 setup with a fast 480GB SSD.

When looking at iostat -v the cache device has only 5GB of allocated space and the rest is free.

Both primarycache and secondarycache are set to all.

How can zfs be set to fill up the cache as much as possible (use most if not all of the 480GB)?

It will use the cache as it's populated and necessary.

If you're not doing much reading activity, you won't see much L2ARC cache usage.
