Hi Johan & All
By design once DDB Re-Sync is initiated you don't need to re-run it (that is why it is greyed out), the default is setting is DDB Re-sync will attempt 5 times and then will report failure.
The purpose of the additional setting "nMaxDDBResyncAttempts" is to allow more retry attempts for the re-sync - in this case "20"
As the issue is still persistent, can you open and share the MediaManager.log (on the CommServe), and filter on "Store [#]", replace [#] with the DDB Engine ID (found as the second expanded option under Deduplication Engine, for the specify Store).
The purpose is to understand why the DDB re-sync is failing/not progressing.
Additional Info - depending on the Service Pack you are on, please ensure the following Hot Fix is applied:
- SP12 - 3297 (DDB partitions may be stuck in resync.)
- SP13 - 1681 (DDB Resync may fail with the error "Unable to validate the DDB files.")
Note - the purpose of restarting Media Manager Service (on the CommServe) can also helps, as we will attempt to send the re-sync request when the service starts up (however this service is used to manage and allocate resource from a CommServe perspective, so suspend any running jobs when doing so).
