HI @Mija :wave:

Welcome to the OpenNebula Forum! :rocket:

In OpenNebula, the hosts do not have an associated storage, instead it’s the datastore the one that contain such information. Hosts in OpenNebula are only viewed as “workload servers” where only their general computational capacity (CPU and memory) is monitored.

This is because depending on the dirvers used, the storage can be defined in different ways: local, shared, ceph, etc.

Is the storage information displayed correctly in the datastores tab in Sunstone? This information can also be seen in the output of the onedatastore show <datastore_id> command.

Best,
Victor.
