I have started using Unraid as a converged data storage and workload environment. The simplicity it provides comes at a cost, which is that I feel the command line interface on the base OS is not well suited to diagnosing problems. An example is that tcpdump is not available, which makes it very difficult for me to diagnose problems. I got around this by creating a container image which slept forever, giving me something to exec into and take actions including running tcpdump. Note: this must be run with Network as Host for tcpdump to run in the host's network context.
