Hello everyone,
I have an oVirt 4.3.2.5 hyperconverged 3 node production environment and we want to add some RAM to it.
Can I upgrade the RAM without my users noticing any disruptions and keep the VMs running?
The way I thought I should do it was to migrate any running VMs to the other nodes, then set one node in maintenance mode, shut it down, place the new memory, bring it back up, remove it from maintenance mode and see how the installation reacts and repeat for the other two nodes. Is this correct or should I follow another way?
Will there be a problem during the time when the nodes will not be identical in their resources?

There is no requirement that your nodes should have the same ammount of RAM. At least my setup doesn't have the same RAM on each node. The problem with nonequal nodes is the scheduling policy, which reminds me to ask if there are any guides for seting a scheduling policy based on memory usage ? Best Regards, Strahil Nikolov
