Move data to USB drive

 Move data partition to USB drive and use SD card as boot partition

1. Backup (Just in case!)
2. Connect the SSD to Pi using the cable
3. Login into Home Assistant CLI over SSH (needs to be via develop port 22222).
4. Get to a host shell using the ‘login’ command.
5. Check the new disk is seen using ‘fdisk -l’, it showed up as an un-formatted disk /dev/sda.
6. Use the datactl command to move the data partition - ‘datactl move /dev/sda’.
7. Reboot as advised by the datactl command output - ‘ha host reboot’.
8. Wait a while - mine took maybe 15-20 mins for a 120GB drive - Home Assistant will eventually boot up

if you have issue wtih SSH then attach keyboard and do it directly 

use root as user name , no password required and enter login to gain access
