and "cachepool" to refer to a cache on a cache pool object. The problem was that the --cachepool option was being used to refer to both a cache pool object, and to a standard LV used for caching. This could be somewhat confusing, and it made it less clear when each kind would be used. By separating them, it's clear when a cachepool or a cachevol should be used. Previously: - lvm would use the cache pool approach when the user passed a cache-pool LV to the --cachepool option. - lvm would use the cache vol approach when the user passed a standard LV in the --cachepool option. Now: - lvm will always use the cache pool approach when the user uses the --cachepool option. - lvm will always use the cache vol approach when the user uses the --cachevol option.
