Hello Ignazio,

The multinode inventory example actually has a storage group [1]. Hosts in this group run the account-server, container-server and object-server Swift services [2], while the control hosts run proxy-server [3]. You can customise each Swift group if you want to control service placement more precisely.

Hello all, I want install swift but I do not have disks on controllers and on compute nodes. Is it possible to inventory a group of servers other than controllers or computes to install swift? 

In other words, I would like to insert in multinode inventory a new group of servers with disks for reinstalling swift.

Thanks.

Ignazio
