 The root filesystem is included in the distributed machine image. It contains the base operating system and the {% data variables.product.prodname_ghe_server %} application environment. The root filesystem should be treated as ephemeral. Any data on the root filesystem will be replaced when upgrading to future {% data variables.product.prodname_ghe_server %} releases.
 
+The root storage volume is split into two equally-sized partitions. One of the partitions will be mounted as the root filesystem (`/`). The other partition is only mounted during upgrades and rollbacks of upgrades as `/mnt/upgrade`, to facilitate easier rollbacks if necessary. For example, if a 200GB root volume is allocated, there will be 100GB allocated to the root filesystem and 100GB reserved for the upgrades and rollbacks.
