" Such options can be set "online": gluster volume set w-vol performance.cache-size 2048MB But I noticed the gluster client will only "notice" them in the logfile (or, gluster client process will start using ~2GB RAM, as expected, with the above cache option set to 2 GB) if it is unmounted/mounted. So: umount /mnt/gluster mount /mnt/gluster Again, please someone correct me if it's needed, as pointed by Papp, documentation seems to suggest is not needed: You can set volume options, as needed, while the cluster is online and available.
