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!

It looks like it thinks my boot partition is also full when it shouldn't be. The numbers aren't adding up (see screenshot).
