The public wiki page which describes how to test Lustre, https://wiki.hpdd.intel.com/display/PUB/Testing+a+Lustre+filesystem, is missing some very critical details. Namely:
- The fact that you need to install "pdsh" on all nodes.
- How you get can "pdsh" especially if on RHLE 7.x (I ended up just building it manually)
- The best approach to dealing with auto-logging in with pdsh (i.e. setting up SSH for auto-login)
- The need to install "ssh-askpass" if it is not present yet
- Changes required if the default first user is not user/group 500:500. RHEL 7.1 has first user as 1000:1000.
- The need to add TCP port 988 to the firewall exceptions list when using TCP
- An example test config file if using real nodes and not just running in loopback.
- Where the tests directory gets installed from the RPM (/lib64/lustre).
- Where do tests get logged by default. It is not at all obvious.
