[one-users] How do i know the cluster's datastore's capacity?

[Kenneth]

You can of course. But it is up to you to monitor. And using storage
on different hosts will cause the VMs to be copied via scp which is
pretty slow. 

Another way to have a large storage is to remove other
drives on the nodes (or use small drives in them) and then plug big
capacity drives on the main NFS node. I mean put everything on the host
A and let other have a small hard drive just enough for the OS itself.

the whole storage capacity is very small,Opennebula can't use other
hosts's disk space.?

That's because you are not using a shared folder for all hosts. A better
way to do it is to make the /var/lib/datastore/1/ folder on the sunstone
as a NFS folder and then mount it all other hosts on the same location
/var/lib/datastore/1/. This will enable you to do live migrations and
very fast deployment of vms.
