Lars.. My environment "needs" of drbd8. Because live migration works flawlessly with pri/pri resources. Using sec/pri I need to do a big trip to achieve this.
sleep the vm put local disk as secondary copy the vm state to remote server put remote disk as primary load the vm state. This procedure takes 20-30 seconds to complish. I can even keep the session (because tcp/ip timeout) With pri/pri I do the following: put remote disk as primary start xen live migration put local disk as secondary The procedure takes 1-3 seconds, and I have only 1 second of delay in session (most of users cannot even notice the migration). My question is: Will be any compatibility with drbd7 and 8? there is a way to migrate drbd7 metadata to 8 without data loss?
