[Linux-cluster] updating nodes and failback oprion



Hello,
I have a 3 Xen nodes cluster + GFS2 (SAN). All VM are in the GFS2 FS.
OS:  just updated to RH 5.4

During the Dom0 update of one of the nodes I used live migration to move VMs to another node. After the update, I rebooted the server. When it came back VMs tried to go back to his preferred node.

I'd like to move back the V.M. manually instead,  is nofailback=1 would do the trick ?

I looking for a wait to :
- booting VM on a prefered node (This part is working)
- If the node fails, the VM is restated on another node (this part is working)
- If the VM is moved (live or relocate) by me or by the cluster because of a node failure. The VM stay on the new node. I will manually move it back after checking 

Regards,

Here is some info abouth the cluster.conf
