------------------------------------------
[~sergey-chugunov] your fix seems to fix my reproducers. Can you please convert
WalDisableTest to JUnit test? Also, can you re-check my own changes in that
branch, especially ClusterCachesInfo one?
> WAL disable/enable with node restarts results in mismatching state, data loss

> Key: IGNITE-13976
> URL: https://issues.apache.org/jira/browse/IGNITE-13976
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.9.1
> Reporter: Ilya Kasnacheev
> Assignee: Sergey Chugunov
> Priority: Critical
>
> If you try to enable/disable WAL on unstable topology, you will get to state
> when WAL status is undefined, nodes might have different wall status and the
> only way to fix it is to restart the cluster, which will lead to data loss
> because ignite removes data if WAL is disabled on restart.
> See the reproducer in PR.
