Troubleshooting Tip: No worker option available after navigating to ADMIN -> License -> Nodes -> Add

[nsoni]

Description	This article describes a solution for an issue where there is no worker option available after navigating to ADMIN -> License -> Nodes -> Add.
Scope	FortiSIEM.
Solution	By design, workers cannot be added to FortiSIEM if the 'EventDB local disk' is used for storage under ADMIN -> Setup -> Storage -> Online -> Event Database. For workers, it is necessary to first switch online storage from the local EventDB to NFS, ClickHouse or Elasticsearch. Sizing Guide References: ClickHouse Sizing Guide. EventDB Sizing Guide.
