Hi, I still don't really understand why this is a client issue not a server issue, but whatever it is it still seems to be present in the latest SP release. A quick recap of the problem as it presented in this case. The disk containing one of the BkgTrigger files was take offline for checks - This was a run 5 collection that had just been imported and so hadn't yet been written to tape. When a client job requested the file the olbd redirected it to one of the stage servers to get if from tape, which obviously failed as did the subsequent jobs. However when the disk was brought back online and the file was once again available 50% of the jobs continued to fail. Looking at the olbd logs I see it redirecting these jobs to the stage server irrespective of the fact that it FAILED to import the file. As far as I can tell the only way to fix this is to stop and start the oblds on both redirectors. Chris.
