--------------------------------
Summary: SCM should not use pipelines with HEALTHY_READONLY
datanodes
Key: HDDS-4992
URL: https://issues.apache.org/jira/browse/HDDS-4992
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
Assignee: Ethan Rose
During upgrade testing for HDDS-4181, it was noticed that datanodes were
incorrectly using the newest metadata layout version when pre-finalized.
However, SCM still came out of safe mode counting these pipelines as healthy,
even though the datanodes' MLV was ahead of SCM's. This Jira will first make
SCM not use pipelines involving HEATLHY_READONLY datanodes. After this is
validated using the current state of HDDS-4181, the issue with datanodes always
using the newest MLV will be fixed.
