Hello all, We are running Apache Ozone as our primary storage system and it has been two years. The cluster has built with a lot of help from the Ozone community. Thank you again for the warm support. This year, we have expanded our Ozone 1.2.x cluster many times but we experienced a disk usage imbalance problem because we have added Datanode incrementally in a small batch. We posted a blog article to share our latest cluster status and "manual" rebalancing maintenance for Ozone 1.2.x. Please take a look. https://tech.preferred.jp/en/blog/two-years-with-apache-ozone/
Thanks, -- Kohei Sugihara, Engineer Preferred Networks, Inc.
