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.

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:
/var/tmp/one/im/kvm-probes.d/monitor_ds.sh kvm /var/lib/one/datastores/
The output should be similar to...
DS_LOCATION_USED_MB=1
DS_LOCATION_TOTAL_MB=9952
DS_LOCATION_FREE_MB=6318
DS = [
ID = 101,
USED_MB = 1,
TOTAL_MB = 9952,
FREE_MB = 6318
]
