Hi,
I am going to manage the virtual machine in environment of Pacemaker-1.0.10.
However, the problem that two virtual machines are started occurs when a
transition graph of "Live Migration" was canceled on the way.
I show a procedure to generate below a problem.
1. I was going to let you do "Live Migration" of a virtual machine from host 1
to host 2.
2. In the middle of "Live Migration", monitor by pingd broke down with host 2,
and an attribute changed.
3. A virtual machine is done start of with host 3 by the management of the
cluster.
Because the virtual machine which moved in migrate_to with host 1 then works, I
am in a condition that two virtual machines start.
This phenomenon thinks that it is revised in Pacemaker-1.1.
I'm not at all surprised that the 1.1 behavior was better, we put a
lot of work into it recently.
If this phenomenon is a bug, I want you to revise it in Pacemaker-1.0.
The necessary patch is quite large and invasive, I don't feel its
appropriate to backport into 1.0.
Will it be not to be able to recommend it in pacemaker-1.0 to move a resource by
setting of "allow_migrate=true"?
Best Regards,
Yuusuke IIDA
