Caching NFS files with cachefilesd

The cachefilesd tool is great for caching network filesystems like NFS mounts! In addition to its ease of use, it provides a substantial amount of stats. For more information, see https://www.kernel.org/doc/Documentation/filesystems/caching/fscache.txt

The following steps will help you cache an NFS mount (this will also work for NFS-Ganesha servers):

Install cachefilesd as a daemon Make sure /etc/cachefilesd.conf is configured correctly. The file does not need to be edited in most cases! It is just a matter of checking the disk limits. The cachefilesd daemon should be started. Mount the network directories using the “fsc” option. If they have already been mounted, unmount and mount them all. A network mount must have the fsc option enabled to enable file caching. Check the stats to see if file caching is working.

In most Linux distributions, it will be almost the same as the example below, which uses Ubuntu 22.04.
