A full host can involve several storage categories whose sizes overlap or use different accounting. Inventory before choosing a cleanup target.

A container can accumulate important files in its writable layer while its named data volume remains small. Inspect changed paths before replacement.

Container logs can consume host space outside an application's data volume. Identify the driver and its managed path before cleanup.

Default logging configuration normally applies when containers are created, not as a guaranteed live rewrite of every existing container.

A tmpfs mount stores temporary runtime data rather than a persistent backup copy. Resource and security implications depend on platform configuration.

Docker
A named volume can exist in metadata while its external storage provider cannot mount it. Inspect the driver before treating it as local data.

Numeric IDs inside and outside a container can differ because of user mapping. Ordinary rootful assumptions may produce incorrect ownership changes.

A dependency can be started while still initializing. Whether Compose waits for readiness depends on the model's supported dependency conditions.
