thanks for reply.

If every node in cluster point it`s /var/lib/sheepdog to the same share 
storage(such as iscsi),can sheepdog work ? Or every node must point 
/var/lib/sheepdog  to diffrent storage?

Hi,can  mutiple sheepdog  nodes  access the same share storage the same 
time? Just like OCFS or GFS2.

It sounds weird to me.
What's the purpose of that?

Sheepdod needs a filesystem with acl supported/enabled.

Or do you mean if two guests can access the same vdi?
In such case the short answer is no.
The long one is:
0.9.x has a locking system, so you absolutely can't.
0.8.3 and previous don't have the locking mechanism, so you can access the 
same vdi from different nodes but you are going to corrupt it if you write 
data from both guests.
