UNTITLED: Footnote 1

These stages create, verify, or remove the tagged files required for a rolling upgrade. The time that it takes to run one of these stages depends on the speed of the member executing the command, the speed of the storage, and whether the member executing the command is the CFS server for the root (`/`), `/usr`, and `/var` file systems. Consider relocating these file systems to the member where you will run the `clu_upgrade` command.
