[jira] [Updated] (IGNITE-26547) Extend test coverage for CMG/MG restarts

     [ https://issues.apache.org/jira/browse/IGNITE-26547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vladislav Pyatkov updated IGNITE-26547:
---------------------------------------
    Description: 
h3. Motivation
Cases of unavailability of system replication groups (CMG, MG) can occur in the cluster involuntarily, for example, when nodes leave the topology, as well as intentionally when the topology is modified by a user with reassignment of system group nodes.
Currently, the system behavior is undefined when any of these system groups are unavailable, and tests for this scenario are absent.

h3. Definition of done
A set of tests should be created to verify the system behavior under system group unavailability.
Implementation will be carried out after the design and support are provided by the system.
