I do a basic series of tests after upgrade including:

This process takes about a day or so to burn in.

-bonnie++

-failover, shutdown of bricks 

-self-heal after simulated brick failure

-Test VMs - similar to those running in production - run unit tests against those VMs

-bonnie++ inside VMs and compare results to previous run.

Nice testing, looks very good to me. You don't expand volume? i.e. add-brick/rebalance?

I'm open to suggestions on other tests though.

I'm running 3.6.1 in pre-production right now.  So far so good.  No critical bugs found.

What tests do you run?

Hi,

I'm curious about the different 'families' of GlusterFS (3.4, 3.5 &
3.6). What's the differences between them and how do I know which one
will be most suitable for my application (depending on if I
prioritize robustness or lots of features)?

Hmm, this is might help from the robustness/features perspective: :)

  * 3.4.x series has been around for ages now, so is pretty battle
    tested.  We still release patch versions for this for important
    bugs which show up.

3.4 has some, imho, critical known bugs with fixes that have already been applied to 3.5 and were not backported. For this lack of support I no longer recommend 3.4.

  * 3.5.x series has been around a while as well, and is also pretty
    well tested by now.  It has more features / and several internal
    optimisations/improvements over the 3.4.x series.  We release
    patches for this series too for important bugs that show up.

This is the version I currently recommend.

  * 3.6.x series just came out.  It's our latest and greatest feature
    set, but may be a bit "bleeding edge" until the next patch release
    (3.6.2), which should be coming out soon.

I'm still waiting on significant reports of success before I'll recommend 3.6. I also watch for bugs that can only be fixed in this release, or lack of support for prior releases, or significant improvements in usability before I upgrade my recommendations.

This makes me realise we really need a version/features table on the
website, with ticks and crosses to show which version of GlusterFS
added what. :D
