We have deployed ignite 2.8.1 in a new azure Kubernetes cluster (version 1.20.9). There are 2 ignite instances and both of them were working fine. But the problem started when we copied few dat files and it’s corresponding bin files (these are basically persistence files) from an old Kubernetes cluster (version 1.18.10) to this new cluster. After data copy one of the ignite instances started failing continuously, however other instance is up & running. In old cluster also ignite 2.8.1 deployed & there are 2 instances of ignite and everything is working perfectly. I am getting following exception –
[IgniteKernal] Failed to start manager: GridManagerAdapter [enabled=true, name=o.a.i.i.managers.discovery.GridDiscoveryManager]
