Why statefulsets do not failover when a node failure happens?

Solution Verified - Updated -

Issue

  • Considering the set up below:
    • Datacenter1: node1: pod1
    • Datacenter2: node2: pod2
    • Datacenter3: node3: pod3
  • When a node failure happens, the pod is stuck on terminating state and is not rescheduled to another node
  • Is not expected to have this pod rescheduled automatically to another node?
