[one-users] Fwd: Add New Storage Box

[Rhesa Mahendra]

Datastore 0 and datastore 2 will be synchronized frontend + nodes (we 
just use persistent image) so i think datastore 0 just synchronized 
symbolic link.
If we have problem maybe existing storage box (datastore 1) broken, all 
vm used new storage box ( datastore 100) will not impact with datastore 
1 because datastore 0 shared and synchronized across frontend +nodes. it 
possible?
