[Gluster-devel] tests/basic/tier/tier.t failure in NetBSD

[Joseph Fernandes]

Hi All,

1. record-metadata-heat.t is already added to bad test: As far as the feature goes its just test the switch
   on the recording of metadata heat. We are aware of the issue here its not the feature but the timing that is used in the test.
   We will be working on it once our priority list of things are addressed.
2. I just had a look at the tier.t failure case. The tests fails at test 45. i.e detach command failure. We can have a look at it and will fix it.
3. Jeff could you please point us to the failure link of fops-during-migration-pause.t so that we can investigate.

Now about tiering test files. Most of the times the tiering tests have failed due to the timing issues of checking status.
i.e synchronizing when file gets promoted and demoted. and its very difficult to have this synchronized with the t file infra (tiering team can add more to this.)
But just to tell that user data is unsafe on this premise would not be correct, as any data loss or corruption or unavailability is already handled in the t files
of tiering.
We will put our best effort to tackle these issues asap.

Regards,
Joe

I just got a similar failure on another (trivial) patch.

https://build.gluster.org/job/rackspace-netbsd7-regression-triggered/14640/consoleFull

My failed-test-analysis script shows the following:

   nine more failures for tier.t
   two for fops-during-migration-pause.t
   one for record-metadata-heat.t

Failures from these tests outnumber failures from all other tests
combined, by a long shot, and I doubt that it's because *any* of the
patches that had to be re-tested had anything whatsoever to do with
tiering.

I propose that tiering and its tests be disabled on NetBSD.  I doubt
that anybody uses the feature on that platform, and this frequency of
test failures suggests that their data would be at risk if they tried.
When tiering on Linux becomes stable, we can consider tiering on NetBSD
as a feature in a future release.
