In Elasticsearch 7.17 is possible to suppress the deprecation warnings by configuring logger.deprecation.level = off in the /usr/share/elasticsearch/config/log4j2.properties file, but in Elasticsearch 8.15 with the same setup they aren't suppressed (for ex. .ds-.logs-deprecation.elasticsearch-default-2024.08.17-000009 index is showing up).
Why is the shard unassigned and how to solve it? Actually I want to remove it...
