[one-users] NFS VM deployment keep getting same error over and over

Fri May 2 07:22:50 PDT 2014

I tried this to move the whole /var/lib/one/ directory to my data store.
however after doing this and mounting it back to the opennebula server and
nodes the whole system crashed :/
nothing worked anymore...
What I did was with the command rsync -aHvz /var/lib/one/ root at datastore
:/var/lib/one
then deleted the /var/lib/one directory on the frontend and mounted it back
so what did I do wrong?
