Hi, I want to reattach an asynchronously replicated EBS volume to Cassandra. I want to know how to fix the delta inconsistency when reattaching other than running a repair on the dataset.
Here is the scenario. Three Cassandra nodes in three separate zones: Node1 --> Zone1 (*EBS_Drive1*, Async_EBS_Drive3_Replica) Node2 --> Zone2 (EBS_Drive2, *Async_EBS_Drive1_Replica*) Node3 --> Zone3 (EBS_Drive3, Async_EBS_Drive2_Replica) EBS replicates data between Zones asynchronously. EBS Drive1 in Zone1 is asynchronously copied to EBS Drive1 in Zone2, and so on. If Node1 goes down in Zone1, I want to reattach Node1's asynchronously replicated drive, *Async_EBS_Drive1_Replica,* in Zone2, which is fine. But this async drive would be missing some of the latest data, say the last 15 minutes, which was present in EBS_Drive1. Besides going through Cassandra repair, what are my options to repair the missing data when I reattach *Async_EBS_Drive1_Replica*? Jaydeep
