Why is a ZFS pool not persisting over server restart?

zpool

I have a ZFS pool with 4 drives. It also has a 3gb ZIL and a 20GB L2ARC that are each partitions on an SDD that doubles as my Linux Mint (ver. 13) boot drive. The pool is mounted to /data.

The problem I am running into is that when I restart the server the pool/directory is completely wiped despite having data in it prior. I'm afraid I'm doing something wrong in the setup, which leads me to the following questions:

What would cause this?
Is there anyway to get the data back?
How do I stop it from happening in the future?

Thank you in advance!

pool: data

state: ONLINE

scan: none
