HI Gianluca,
 Glad to hear that your problem is solved. As you redeployed Hosted Engine , default gluster service is not enabled in cluster because of that you are not able to see gluster volumes.
Please edit cluster in admin protal and select the checkbox "Enable Gluster service" and save, your problem will be resolved :)

Thanks Gobinda, it worked like a charm.
Actually I was indeed searching for it remembering in the past, but I was misled by firefox showing a corrupt page: for this problem I'm going to open a distinct thread.

Do I need to restart engine service?
Because I can go into Storage --> Volumes but as soon as I click inside one if them (eg engine) I get a gui exception (Chrome 86.0.4240.111 (Official Build) (64-bit) on Fedora 31 google-chrome-stable-86.0.4240.111-1.x86_64)
See here:

Conversely instead Firefox 82 (firefox-82.0-4.fc31.x86_64) doesn't show this GUI exception....
