[one-users] System volumes created with no space

[Ruben S. Montero]

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.

The monitoring probes (take a look to monitor_ds.sh in
/var/lib/one/remotes) looks for DATASTORE_LOCATION, not BASE_PATH...

Cheers
