Description of problem:
---------------------------------------
Consider a cluster created via the Console, having a host (say host1) added to it, such that host1 already has a peer. 
Output of 'gluster peer status' on host1 - 

Number of Peers: 1

Hostname: 10.70.35.68
Uuid: 6b2235c3-543f-4e08-90c4-634069751124
State: Peer in Cluster (Disconnected)

Now add another host (say host2), to this cluster, such that host2 also has a peer. Output of 'gluster peer status' on host2 - 

Number of Peers: 1

Hostname: 10.70.35.90
Uuid: 0131251d-7a9e-490f-a628-ce01a8216c1e
State: Peer in Cluster (Disconnected)

host2 after going through the process of installing and reboot, comes up. Then, host1 disappears from the UI with the following message on the Events log - 

"Detected server host1 removed from Cluster TestCluster, and removed it from engine DB."

Version-Release number of selected component (if applicable):
Red Hat Storage Console Version: 2.1.0-0.qa6.el6rhs 

How reproducible:
Intermittent

Steps to Reproduce:
1. Add host1 to the cluster such that it has a peer in the Disconnected state.
2. Add host2 such that it also has a peer in the Disconnected state.
  
Actual results:
After host2 comes UP, host1 gets disappeared from the UI.

Expected results:
host2 coming UP, should not result in host1 getting disappeared from the UI.

Comment 6 Shireesh 2013-04-17 11:47:44 UTC 
Sent upstream patch for validating that the new server being added is not part of another cluster. http://gerrit.ovirt.org/13980
Comment 7 Shruti Sampat 2013-04-25 10:37:15 UTC 
Verified as fixed in Red Hat Storage Console Version: 2.1.0-0.qa10.el6rhs.
The Console now displays the following error message when trying to add a host that is part of another cluster - 

"Error while executing action: Server <IP> is already part of another cluster."
