Managing Your Cache File Systems With cachefspack
For general use, CacheFS operates automatically, without requiring any action from the user. Files are cached on a most recently used basis. With the packing feature, you can take a more active role in managing your cache by ensuring that certain files or directories are always updated in the cache.
Packing enables you to specify files and directories to be loaded in the cache. It ensures that current copies of these files are available in the cache.
The packing list contains the names of specific files and directories. It can also contain other packing lists. This saves you having to specify individual files and directories in case you have many items to pack in your cache.
The cachefspack command provides you with added control of your CacheFS file systems, employing the packing functionality.
