Option 3: You split the index , which amounts to increasing the shard number for that domain. Note: this option requires scheduled maintenance window as the index needs to be in read-only mode during this split process. Veeam v12.1 introduced a new feature to temporarily disable background retention, you will need to activate this during the split operation. ( See https://helpcenter.veeam.com/docs/backup/vsphere/backup_background_retention_disable.html?ver=120 ) For more details see: TODO final link [DRAFT] Steps to split or reduce the number of shards in perdomain index /wiki/spaces/~5f4d1b7773a268004df5fcac/pages/3696558130 |

Keep in mind that splitting an existing index will increase the shards it uses and account towards the maximum 600 shards per node limit. |

In the example above we had 5 data nodes, with 600 shards per node this means Swarm can support up to 250 domains ( some indexes indices are needed for csmetrics, kibana, etc.. )
