Hi Everyone!
I did a test upgrade from SharePoint 2010 to SharePoint 2013. Basically everything went pretty well except that accessing files in a document library isn't possible anymore. The browser keeps loading and after about a minute the connection gets resetted.
The ULS states the following error message:
Failed in CobaltStream.LockBytes: ErrorException: Eine Ausnahme vom Typ "Cobalt.ErrorException" wurde ausgelöst. --- Error: InvalidSerialization --- Error message: Unknown element id at bei Cobalt.DataElementGraphOnEndpoint.Download() bei Cobalt.DataElementGraphOnEndpoint.OnGetIndexEntry(Key key, IndexEntry& indexEntry, Int32& refCount, Int32& chainRefCount) bei Cobalt.DataElementGraph.FindIndexNode(Key key) bei Cobalt.DataElementGraph.FindIndexNode[TIndexNode](Key key) bei Cobalt.CellGraph.Load(Boolean allowSchemaChange) bei Cobalt.GenericFda.Refresh(Boolean onlyIfFirstTime, Boolean allowSchemaChange) bei Cobalt.GenericFdaHandler.GetStream(ExtendedGuid streamId, Bytes& bytes) bei Cobalt.FdaManager.GetStreamInternal(ExtendedGuid streamId) bei Cobalt.OnDemandBytes.get_TheBytes() bei Cobalt.OnDemandBytes.Read(Range rangeToRead, Byte[] buffer, Int32 offset) bei Cobalt.Bytes.Read(Int64 sourcePosition, Byte[] buffer, Int32 offset, Int32 count) bei Cobalt.Bytes.ReadIfPossible(Int64 sourcePosition, Byte[] buffer, Int32 offset, Int32 count) bei Microsoft.SharePoint.LockBytesFromBytes.ReadAt(Int64 offset, Byte* pv, UInt32 cb, UInt32& pcbRead) bei Microsoft.SharePoint.CobaltStream.ReadAt(Int64 offset, Byte* pv, UInt32 cb, UInt32& pcbRead)
Searching on Bing or Goolge did not gave me any results.
Any ideas or suggestions?
Thanks in advance!
