<div dir="ltr">Could it be the mount points? Datastores on the hosts have to be mounted under DATASTORE_LOCATION as defined in oned.conf (defaults to /var/lib/one/datastores). Note that BASE_PATH refers to the path used to store the images when they are resitered (not needed for a system ds). Roughly you go from BASE_PATH/<image_uuid> in the datastore to DATASTORE_LOCATION/<DS_ID>/<VM_ID>/disk.0 in the hypervisor.<div>

</div>I do have a healthy hypervisor which is being monitored, which has both<br>
shared NFS volumes.<br>
<br>
[oneadmin@snow-opennebula01 ~]$ onehost list<br>

<br>
Having looked in oned.log I see no reference to the original system<br>
volume being mentioned. But the second system volume I created is being<br>
successfully monitored:<br>
<br>
# grep system oned.log | tail<br>

But systems_nfs reports have no space available either. (As seen in my<br>
original query.)<br>
