Metadata store replica already in use, still!

Question

Hi,

Got a slightly infuriating, but not entirely uncommon problem which has been brought up before however not solved in a way that works in my application.

I have a method which does the following:

            public void InitiateSync()
            {
                FileSyncProvider sourceReplica;
                FileSyncProvider destReplica;
                SyncOrchestrator so;
                String MetaDataDirectory = "./Metadata";

                sourceReplica = new FileSyncProvider(this.LocalDirectory,
                    this.filter,
                    this.options,
                    MetaDataDirectory,
                    "source.metadata",
                    Path.GetTempPath(),
                    this.ConflictDirectory);
                destReplica = new FileSyncProvider(
                    this.RemoteDirectory, 
                    this.filter,
                    this.options,
                    MetaDataDirectory,
                    "remote.metadata",
                    Path.GetTempPath(),
                    this.ConflictDirectory);

                so = new SyncOrchestrator();

                try
                {
                    so.LocalProvider = sourceReplica;
                    so.RemoteProvider = destReplica;
                    so.Direction = SyncDirectionOrder.DownloadAndUpload;
                    // Explicitly detect changes on both replicas upfront, to avoid two change 
                    // detection passes for the two-way sync
                    //sourceReplica.DetectChanges();
                    //destReplica.DetectChanges();

                    so.Synchronize();

                    OnComplete(); // Fire the Complete event to notify clients
                }
                catch (Exception e)
                {
                    OnError("Sync Exception: " + e.ToString()); // notify clients of an error
                }
                finally
                {
                    if (sourceReplica != null)
                    {
                        sourceReplica.Dispose();
                        sourceReplica = null;
                    }
                    if (destReplica != null)
                    {
                        destReplica.Dispose();
                        destReplica = null;
                    }
                }
            }

I am getting a ReplicaMetadataInUseException thrown at me, either from the constructors of FileSyncProvider, or by SyncOrchestrator.Synchronize(). It appears to mainly happen if one of the replicas change when my application is not running. Why this makes any difference I don't know - the FileSyncProvider objects should be garbage collected as soon as the method ends, and I have .Dispose()'d them and even set them to null (as recommended in the other post, Metadata store replica is already in use!!!)

So it looks like something is not closing the metadata store properly when I'm disposing of the FileSyncProvider objects. As you can see, it's just the standard builtin metadata source, which to make life a bit easier I'm putting in a specified local directory.

Also, there's definitely not any other processes accessing the metadata stores.

I've also looked at Overcome Error: "The metadata store replica is already in use" which also hasn't really helped a lot.

Thanks!

Hi,

I got stuck with similar issue (Metadata store replica is already in use) details as below

I am using one power shell script to synchronize users profiles' IE favorite content to a particualr folder in his/her home profile path in file server.

I have Download and install Microsoft Sync Framework 2.1(x86 or x64) from http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=19502 with following sequence: Install 1 and then 2

Synchronization.msi: includes managed and native API for the synchronization runtime, core components, and Web synchronization components. This package is a pre-requisite for the other packages and must be installed first.
ProviderServices.msi: includes managed and native API for simple custom providers, the file synchronization provider, the metadata storage service, and also DLLs for the lightweight database that the storage service uses.

I have also used the .dispose() fundtion to release resources, but not result.

My script is as below:-
