      Description

      It might be more versions but I have only tested this on 2.x.

      Essentially when trying to find replicas to copy blobs from LocalFSBlobStore does not exclude itself. This results in a deadlock where it is holding a lock trying to download the blob, and at the same time has done a request back to itself trying to download the blob, but it will never finish because it is blocked on the same lock.
