ASF GitHub Bot updated HDDS-6695:
---------------------------------
Labels: pull-request-available (was: )
> Enable SCM Ratis by default for new clusters only
> -------------------------------------------------
>
> Key: HDDS-6695
> URL: https://issues.apache.org/jira/browse/HDDS-6695
> Project: Apache Ozone
> Issue Type: Improvement
> Components: SCM HA
> Reporter: Ethan Rose
> Assignee: Swaminathan Balachandran
> Priority: Blocker
> Labels: pull-request-available
>
> HDDS-5740 (Enable ratis by default for SCM) has been reverted, since it will
> cause the upgrade framework to fail SCM startup on upgraded clusters where
> SCM HA/SCM Ratis is not yet finalized. Since it is always possible and
> supported to upgrade an older version of Ozone from before the SCM HA layout
> feature to a version of Ozone with the SCM HA layout feature, this option can
> never be the default for upgraded clusters.
> However, for new clusters, even those that do not explicitly configure HA, it
> is best to use Ratis by default for SCM as noted in HDDS-5740 so that a
> non-HA SCM setup can easily be bootstrapped to an HA setup later.
> This Jira is to make the config key {{ozone.scm.ratis.enable}} default to
> true for new installations, and false for for existing non-HA/non-Ratis
> installations.
