ZFS - Pools - Use Encryption with a ZFS Pool

After creating a ZFS storage pool, encryption can be enabled on it.

sudo zfs create -o encryption=on -o keylocation=prompt -o keyformat=passphrase testpool/encrypted

NOTE: You will be asked to enter the passphrase twice.

NOTE: A new directory will be created under the storage mount point and anything under this directory will be encrypted.

Whenever the system is rebooted, you may need to manually mount the dataset.
Remember to use the -l flag when mounting the encrypted dataset.
You will be prompted for the passphrase, supply the passphrase you have used to encrypt the pool, and continue.

sudo zfs mount -l testpool/encrypted
