When a target volume is replaced, there is no data on the new target volume. However, DataKeeper will re-establish the mirror when the Source node is able to communicate with the Target, and will perform a partial resync. This results in incomplete and corrupt data on the target.
To resolve this issue, a full resync needs to be performed. Open the DataKeeper GUI, locate the mirror from the Source to the Target (inside the appropriate job), right click the mirror and choose “Resync Mirror”.
