We saw data loss when we added two new nodes(same time) in 3-node cluster during live traffic.Our aerospike cluster is using shadow devices.
We started these two new nodes with 8hr older backup( EBS snapshot). After migration completion, we observed that for few records there is data loss of last 8hrs. I guess, older records( from backup) replaced new records during migration but don’t know how.
did this happened because we added both boxes at same time?
