This option can cause silent failures which are confusing and hard to track down. While the intention of this was to allow large scale deployments to succeed in cases where a single node fails due to transiant issues it has produced more problems in terms of confusion that it solves. This change removes the option from all production playbooks. Change-Id: I1dcbbf5bc8cc66f11dd8ddc22d2a177c5c0f31f1 Signed-off-by: Kevin Carter <kevin.carter@rackspace.com>

|
|
- The `max_fail_percentage` playbook option has been used with the default
|
|
playbooks since the first release of the playbooks back in **Icehouse**.
|
|
While the intention was to allow large-scale deployments to succeed in
|
|
cases where a single node fails due to transient issues, this option has
|
|
produced more problems that it solves. If a failure occurs that is transient
|
|
in nature but is under the set failure percentage the playbook will report a
|
|
success, which can cause silent failures depending on where the failure
|
|
happened. If a deployer finds themselves in this situation the problems are
|
|
are then compounded because the tools will report there are no known issues.
|
|
To ensure deployers have the best deployment experience and the most
|
|
accurate information a change has been made to remove the
|
|
`max_fail_percentage` option from all of the default playbooks. The removal
|
|
of this option has the side effect of requiring the deploy to skip specific
|
|
hosts should one need to be omitted from a run, but has the benefit of
|
|
eliminating silent, hard to track down, failures. To skip a failing host
|
|
for a given playbook run use the `--limit '!$HOSTNAME'` CLI switch for the
|
|
specific run. Once the issues have been resolved for the failing host rerun
|
|
the specific playbook without the `--limit` option to ensure everything
|
|
is in sync.
