• Correlation between job stats and LNet stats
• RDMA issues in mixed mlx4 with Lustre 2.5 + FDR and mlx5 + Lustre 2.10 + EDR clusters
• Router configuration on CEA. Ability to select routers based on policy. Add this to the UDSP project requirements.
• MR routing, entire system needs to be configured with MR in order for it to work across routers.
  • I thought that the selection algorithm should care about the next hop. So we need to look into that.
• NASA wants to export a directory from a secure Lustre FS to the public (over the internet). Currently they do that by exporting the directory over nfs to another client which mounts a different Lustre FS.
  • Is there a way to do it within lustre securely
  • sub-directory mount
  • but it's not secure in case of compromised root client.
  • Use V-lans to lock the UUID and GID
  • but that doesn't prevent the client from guessing a FID and read a different insecure file.
  • using nodemaps to remap GID/UUID
  • using root squash.
  • According to JohnH there is some work needed on the nodemaps in order to close the hole above.
