# What storage is available at /mnt/home and /mnt/data?

SUNK provisions a shared home directory mount at `/mnt/home` by default (default size 2 TiB), defined through `spec.storage.homeDir` in the `SunkCluster` resource. The mount is `ReadWriteMany` and is automatically mounted on every login pod and compute Node, so files written from one Node are visible from every other Node.

`/mnt/data` is a common convention used in CoreWeave tutorials, but it is **not** a default mount. To make it available, add it to `spec.storage.additionalMounts` when creating the cluster.

For details on configuring additional shared volumes, see [Share storage across Slurm nodes](/products/sunk/manage_sunk/shared-storage) and the [`SunkCluster` storage reference](/products/sunk/reference/sunkcluster-reference#storageconfig).
