[Xen-users] Xen-DRBD Migration question
Hi,
Let me introduce our setup so you can have a better ideas on my situation.
We have 2 physical hosts. Both have Xen for the vm and as for the disk, we have
DRBD that sync between the two host. We would like to be able to do migration
or live migration between host. This is possible as we have successfully done
it.
As we can read on documentation and all is that migration and live migration is
done with --allow-two-primaries options on DRBD. Unfortunately and for obvious
reasons this option is too dangerous to be left on and we would like to avoid
using this at all cost.
I've heard from a post somewhere that a migration Secondary-Primary can be
done. Our best way to do this will be to put de VM on pause. Put the drbd disk
on Secondary. Then migrate the vm to the second host, then put the drbd disk on
second host to primary and unpause the vm. I've searched on google and I can't
find anything on this method.
Is there a way to do this? Is there another way you are thinking of?
Thanks for you help,
