Creating a storage

A storage consists of two parts: one part is created inside the KUMA console, and the other part is installed on network infrastructure servers intended for storing events. The server part of a KUMA storage consists of ClickHouse nodes collected into a cluster. ClickHouse clusters can be supplemented with cold storage disks.

For each ClickHouse cluster, a separate storage must be installed.

Prior to storage creation, carefully plan the cluster structure and deploy the necessary network infrastructure. When choosing a ClickHouse cluster configuration, consider the specific event storage requirements of your organization.

It is recommended to use ext4 as the file system.

A storage is created in several steps:

1. Creating a set of resources for a storage in the KUMA console
2. Creating a storage service in the KUMA console
3. Installing storage nodes in the network infrastructure

When creating storage cluster nodes, verify the network connectivity of the system and open the ports used by the components.

If the storage settings are changed, the service must be restarted.
