mds01@tcp0:mds02@tcp0:/testfs - that works, thanks for spotting this:
https://build.hpdd.intel.com/job/lustre-manual/lastSuccessfulBuild/artifact/lustre_manual.xhtml section "37.15.3. Options" - "The MGS specification may be a colon-separated list of nodes."
So there is a typo at page 26 of http://www.dell.com/downloads/global/solutions/200-DELL-CAMBRIDGE-SOLUTIONS-WHITEPAPER-20072010b.pdf

By they way are there any public lustre integration tests that can be used as a base for documentation?

Failover examples in the lustre manual use “:” to separate the server nids instead of the “,” that you are using. Have you tried that?
