I don't remember installing it. I've checked the installation on another machine on which I recently installed Fedora-27 on bare hardware;

$ rpm -qa | grep gluster

doesn't show anything, so I must have done something to cause the gluster filesystem to be installed.

Is there any reason not to remove it?  

On the other hand, is gluster useful for some particular purpose? For example, can it be configured as a backup system to protect a computer against ransomware, etc?

Here are the results of the commands you asked about:

$ rpm -qf /usr/lib/tmpfiles.d/gluster.conf

glusterfs-3.12.4-1.fc27.x86_64
$ rpm -qa | grep gluster
