[Gluster-infra] Recent regression failures

[Nigel Babu]

Hello folks,

We may have been a little too quick to blame Meltdown on the Jenkins
failures yesterday. In any case, we've open a ticket with our provider and
they're looking into the failures. I've looked at the last 90 failures to
get a comprehensive number on the failures.

Total Jobs: 90
Failures: 62
Failure Percentage: 68.89%

I've analyzed the individual failures categorized them as well.

slave28.cloud.gluster.org failure: 9
Geo-replication failures: 12
Fops-during-migration.t: 4
Compilation failures: 3
durability-off.t failures: 7

These alone total to 35 failures. The slave28 failures were due to the
machine running out of disk space. We had a very large binary archived from
an experimental branch build failure. I've cleared that core out and this
is now fixed. The geo-replication failures were due to geo-rep tests
depending on root's .bashrc having the PATH variable modified. This was not
a standard setup and therefore didn't work on many machines. This has now
been fixed. The other 3 were transient failures either limited to a
particular review or a temporary bustage on master. The majority of the
recent failures had more to do with infra than to do with tests.

I'm therefore cautiously moving with the assumption that the impact of KPTI
patch is minimal so far.
