<div><br></div><div>About Mount Points</div><div><br></div><div>They **must** use the same ID as the one assigned by OpenNebula. So if you want datastore with ID 100 be backed by datastore1 (192.168.8.11), then you must mount the volume on <div class="gmail_default" style="font-size:small;display:inline">
</div>/var/lib/one/datastore/100. Same apply to 0,1 default and system datastores created by OpenNebula by default.</div>
<div><br></div><div>About Datastore Types and Usage<br></div><div><br></div><div>There are two types of Datastores: Images where you usually store base images (e.g. default ID:1) and system where the VMs run from (e.g. system ID:0). And there are three types of images: persistent no copy from image to system datastores (link); no-persistent images are copied (cloned) to the system datastore; and volatile disks, always created in the datastore.</div>
<div><br></div><div>Summary, register an image (oneimage create) will take space from your image DS, deploying a vm (onevm deploy) will take space from your system DS. How much space? It depends on the image (persistent vs non-persistent) and the format raw vs qcow2.</div>
<div><br></div><div>You also need to consider that checkpoints (suspend/stop a VM) will generate a checkpoint file to be stored also in the system DS</div><div><br></div><div><br></div><div>Hope you can now plan better your storage.</div>
