The system DS is not supposed to show up with any space until a host is<br>
configured? That is a surprising because the pre-configured sandbox<br>
instance I downloaded first for testing (a Virtualbox instance) has<br>
space listed in the system DS even though that has no hosts connected to<br>
it.<br></blockquote><div><br></div><div>I'm not sure about the sandbox configuration (e.g. there were some data from the setup). Anyway, system DS is monitored from the hosts. Note that System DS is not need (not even accessible for some storage backends) in the front-end, so the space is reported by the hosts. Also System DS is used to run VMs from it, and mainly used in the hosts.</div>

In any case, there are no hosts connected to the test instance that I<br>
gave the example on, but on some other instances which I have configured<br>
elsewhere do have hosts configured and they have the same problem. I<br>
have /var/lib/one as a NFS mount that is mounted on both the frontend<br>
and the node. That instance comes up with no space in the system DS as<br>
well.<br></blockquote><div><br></div><div>This may be a problem with the configuration or the sytem DS not properly mounted in the hosts. The information is obtained with /var/tmp/one/im/kvm-probes.d, go to the host kvm04 and execute:</div>

Here is some output from that showing the system DS with no space even<br>
though the logs say the node is successfully monitored:<br>
