Hi, Andrew

Thank you for an reply.
When a multiplex virtual machine is started in my environment, a disk may be broken.
This is fatal.
Because there is no help for it, I intend to apply it in "allow_migrate=false".

Thanks,
Yuusuke IIDA

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"?

Well you can set that and if the RA doesn't fail everything will be happy.
But as you saw, the recovery characteristics if/when part of the
migration fails are not ideal.
