Replace a single drive.

[gunnahafta]

I presently have a pool in my Freenas on a single 3TB drive. I want to replace this 3TB drive with a larger 8TB drive. I thought I could add the larger drive to the pool or maybe as a mirror. Then remove the older drive but will I then basically waste the extra 5TB?

How can I move from the old drive to the new drive without breaking all the paths, acl's, VM's, jails etc or waste the extra storage space?

And yes I am aware of the danger of having a single drive but its not critical data so I am not worried.

Move the System Dataset to the boot-pool.
Attach the 8TB drive as a new pool.
Do a replication from the old pool to the new one.
Export both pools.
Import the 8TB pool changing its name to that of the old one.
Clear the dataset Read-Only setting and you should be good to go.
If you get stuck the old 3TB will still have all the data.
