zpool add existing-pool mirror /dev/sdb /dev/sdc

Check the dataset seize

sudo zfs list mypool/dataset

Set additional properties

sudo zfs set compression=on mypool/mydataset # turns on compression
sudo zfs set quota=10G mypool/mydataset # set the sixe quota to 10GB
sudo zfs get quota /mypool/mydataset # view the quota of the dataset
