glusterd = management daemon
Главный демон, управляет томами, тянет за собой остальные демоны, отвечающие за брики и восстановление данных.

glusterfsd = per-brick daemon
У каждого брика запускает свой glusterfsd демон.

glustershd = self-heal daemon
Отвечает за ребилд данных у реплицированных вольюмов в случаях отвала нод кластера.

glusterfs = usually client-side, but also NFS on servers. Part of glusterfs-fuse rpm package.

[gluster-block](https://github.com/gluster/gluster-block) is a CLI utility, which aims at making Gluster backed block storage creation and maintenance as simple as possible.
