I believe you ran this command on 002? And in that case its showing as localhost. > We're not using snapshots so I guess this is fine too? Is features.uss enabled for this volume? Otherwise we don’t show snapd information in status output. Rafi - am I correct? Yes. We don't show snapd information unless uss is enabled. So please check whether uss is enabled or not. You can use gluster v get glusterfs features.uss . If you are not using any snapshot then it doesn't make sense to use uss. You can disable it using gluster v set glusterfs features.uss disable Please note that if you are doing the rolling upgrade, it is not recommended to do any configuration changes. In that case you can disable it after completing the upgrade.
