Each attendee typically has their own perspective on these events. I encourage others to report their impressions. This was a 100% virtual event due to industry-wide constraints on travel funding. A Tailscale VPN was deployed for the event, and spanned from the west coast of North America to European countries. Event organizers are planning to leave this infrastructure in place so that ad hoc testing can happen at any time. We continue to find that regular week-long mass testing events are valuable. Raw testing results were collected in a Google doc: https://docs.google.com/spreadsheets/d/1_BWbwEBqmWGgp1zbWXOILgYTJjowRlhNichNLY_xLqs/edit#gid=0 Attendees brought several implementations, though the test population was heavy on Linux. A variety of test suites were employed, including the Linux community's xfstests, Mora's nfstests, the git tool's regression suite, and the venerable Connect-a-thon suite. My primary interest at this event was testing the Linux RPC-with-TLS implementation. I brought both a client and server implementation. I used my client with the other TLS-enabled servers present at this event. My testing was with NFSv4.1, driven by the git regression suite workload. It was largely successful with each server that could run that workload without TLS. Olga Kornievskaia tested a Linux client very similar to mine with Kerberos user authentication and TLS, and pNFS and TLS. No significant or unexpected issues were found. NetApp was able to provide an iWARP-enabled OnTAP server. I tested with a Linux NFS/RDMA client using the same git regression workload without issue. Stock Linux is still unable to support the combination of a soft iWARP device with a VPN tunnel device. A small local code change was necessary to enable testing at this event. I am pursuing the issue with the soft iWARP driver's maintainer as well as upstream Linux's RDMA community. -- Chuck Lever
