Creating an Encrypted Pool
When we built the pool, we only used a small portion of the RAID 1 mirrored array. That left us with room to build a separate pool. This time we're building an encrypted pool using the same drives, while the first pool is still on the drives.
The process is very similar to building the initial pool on the previous page.
This time we need to add a password to our creation.
Again, we used thin provisioning, so we're only using the space we need at the time.
