You should be able to use cloudstack to move a VM from Local Storage to shared storage. but you might need to unmount the data disk and perform this task with the VM as shutdown as the Migrate Instance button will allow you to specify the Storage. Regards, On Wed, Jun 3, 2015 at 9:18 PM, Ahmad Em

I'm not sure whether that's configurable and I haven't seen any examples out there that point to it being configurable. Having said that, there are people a lot more familiar with that than I am on the list. One option you do have for this particular failure situation, is to use monit to monit

Exactly...thanks Simon for the time and help :) Is there any mysql timeout/retry parameter that is set in db.properties (like db.cloud.queriesBeforeRetryMaster=5000), but I'm wondering since I'm using keepalived/haproxy setup, it takes up to 5-6 sec for keepalive to detect haproxy is down (while t

Personally, I think that Gallera is always going to be a safer option, as it handles conflict resolution natively. Having said that, it appears care has been taken in designing the ACS MGMT DB integration so that the chance of conflicts is very low. Galera requires a 3 nodes minimum, so it's a
