Discovery disabled 4-4: implicit discovery of an MR peer

  • MR Node with interfaces N1, N2
  • MR Peer with interfaces P1, P2, P3
  • Discovery is disabled on both Node and Peer
  • Force some filesystem traffic between node and peer.
  • Verify that node sees one peer with one NID: P1.
  • Verify that peer sees node as one peer with one NID: N1.
   

Discovery disabled 4-5: implicit discovery of an MR peer.

(This test shows that if discovery is enabled on either node or peer, it happens on both.)

  • MR Node with interfaces N1, N2
  • MR Peer with interfaces P1, P2, P3
  • Discovery is disabled on Node
  • Force some filesystem traffic between node and peer.
  • Verify that node sees one MR peer with NIDs: P1, P2, P3
  • Verify that peer sees node as one peer with NIDs: N1, N2.
   

Discovery disabled 4-6: implicit discovery of an MR peer, > 16 interfaces.

(This test shows that if discovery is enabled on either node or peer, it happens on both, including retries required because buffers need to be extended.)

  • MR Node with interfaces N1, N2, ..., N17
  • MR Peer with interfaces P1, P2, ..., P17
  • Discovery is disabled on Node
  • Force some filesystem traffic between node and peer.
  • Verify that node sees one MR peer with all NIDs: P1, P2, ..., P17
  • Verify that peer sees node as one MR peer with all NIDs: N1, N2. ... , N17.
