    GUI
    Install drive -> Storage Disks -> Wipe (Short)
    Raid Management -> Select Raid -> Recover -> Add new drive
    When sync has finished Raid Management -> Select the raid -> Grow
    Then, File Systems -> Select the raid -> Resize

    Raid is not a backup! Would you go skydiving without a parachute?

    Does this instruction delete the data ? I mean the "Wipe (Short)" is whats driving my question.

  • As @henkall already has explained the wipe part is only for the new drive which you intend to add to the array.


    But it is highly recommended to have a full data backup if you modify your RAID setup. Because anything can happen which may lead to a complete data loss.
