A caching filesystem (as opposed to a standard block storage filesystem) would be one used for cached data specifically. ZFS has cache drives but the actual on disk layout does not resemble ZFS as we know it. That’s what I’m eluding to; ZFS in this case is an all-in-one solution so it’s perfectly fine to refer to it as a feature of the filesystem, but externalising that to a separate agnostic product would result in this being exposed. In fact CacheFS was designed exactly like this, and as you can see includes both “cache” and “FS” in the name. https://lwn.net/Articles/100330/ |
