# Single Disk Data Migration to ZFS Mirror

Starting Point :
Single XFS HDD with a whole bunch of Data..

Planned Setup:
ZFS Mirror without loosing any Data..

### Save your Data

First things first: **DO A BACKUP !!**
and then 5 more just to be absolutely sure!

1. create single ZFS drive: **zpool create -m /data data /dev/sdb**
2. copy data on it: **cp/rsync/whatever floats your boat**
3. empty and wipe the disk, which you basically just cloned
4. find your empty drive using: **ls /dev/disk/by-id/**
5. add it to the pool: **zpool attach Pool\_Name Filled\_Drive\_Name Empty\_Drive\_Name**

Once done you can check it with **zpool status**.
After a couple seconds it should say that it's "resilvering" the new drive.
Meaning it started creating the Mirror.
Since we are copying all the data 2 times altogether the whole process can take quite some time!
