# Changes

  • In this release, a change will be implemented to the device node naming convention for virtual drives. The current naming convention, /dev/gvdXnX, will be replaced with a new convention, /dev/gdgXnX. Additionally, virtual drives within the same drive group will be treated as separate namespaces. For instance, if there are two virtual drives in drive group 0, their device node names will be /dev/gdg0n1 and /dev/gdg0n2
