   @pyttel that makes sense, I understand the difficulties due to the clashes 
between the design of Kubernetes and Raft. But here we are assuming that the 
volume (pv/pvc) in which the OM or SCM store their data can be moved around. In 
a case where we are storing the data locally on the host machine, this would 
not be possible. Say a node goes bad, then kubernetes would choose a different 
node for the OM or SCM to come up. But on this node, the metadata isn't present 
=> we lose the data. This is where HA is needed. 
   Hence this decision should be based on the type of storage the user 
configures. Given we choose local storage, I think an option of HA would be 
needed.
   What StorageClass have you been using for your deployments? 
   
   A kubernetes operator would work as well, but I haven't done enough research 
on that to give a strong opinion. If I am not mistaken, that would take a 
bigger effort than the current PR. Maybe eventually if we can have both options 
that would be better?
