Ethan Rose created HDDS-8380:
--------------------------------
Summary: Add CLI to dump Ratis state from each node
Key: HDDS-8380
URL: https://issues.apache.org/jira/browse/HDDS-8380
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
Idea proposed by [~swagle]: Right now debugging quorum issues and lagging
followers requires filtering logs on all 3 members. It would be easier if there
was a command that could be sent from the CLI to get information from all
members. This could include:
* commit index
* apply index
* snapshot index
* current term
* group membership (as defined in raft-meta.conf)
* Known leader
* Known follower's commit indices if leader
This could be implemented from the [ratis
shell|https://github.com/apache/ratis/blob/master/ratis-docs/src/site/markdown/cli.md],
but it may be easier for users if it is packaged within the ozone CLI under
{{ozone debug}}. One challenge may be getting results from all nodes, since
right now ozone client only communicates with the leader of the quorum.
