How to handle dual primary data corrupt
We use vrr + vgcm to build a dr solution for oracle db. There are two sites , each site including one server with a storage(will call server A, B). When A is crash, B will take over the service and bring the rvg to primary. But if the data in A's volume is not fully synced to B (for example, low network bandwith); since B is taking over the db to run the job, data in B's volume will be changed . And then data corrupt occurs.
Does anyone have a solution to hanle this data corruption?
