Setting this to an externally-facing URL that is protected by auth middleware (e.g. OAuth2 proxy, ingress auth) will cause internal components to receive an HTML redirect instead of JSON, resulting in "invalid character '<'" errors and CSI driver deployment failure. Use this setting only when the URL is accessible unauthenticated from inside the cluster. Format: scheme://host[:port] (for example, http://longhorn.example.com).

  v1DataEngine: ~
  # -- Setting that allows you to enable the V2 Data Engine, which is based on the Storage Performance Development Kit (SPDK). The V2 Data Engine is an experimental feature and should not be used in production environments.
  v2DataEngine: ~
  # -- Applies only to the V2 Data Engine. Enables hugepages for the Storage Performance Development Kit (SPDK) target daemon. If disabled, legacy memory is used. Allocation size is set via the Data Engine Memory Size setting.
  dataEngineHugepageEnabled: ~
  # -- Applies only to the V2 Data Engine. Specifies the hugepage size, in MiB, for the Storage Performance Development Kit (SPDK) target daemon. The default value is "{"v2":"2048"}"
  dataEngineMemorySize: ~
  # -- Applies only to the V2 Data Engine. Specifies the CPU cores on which the Storage Performance Development Kit (SPDK) target daemon runs. The daemon is deployed in each Instance Manager pod. Ensure that the assigned CPU cores do not exceed the guaranteed CPUs allocated to the V2 Data Engine Instance Manager. A minimum of 2 CPU cores is recommended. SPDK uses a busy-polling reactor model where the master reactor handles both I/O polling and management RPCs. When only a single core is assigned, heavy I/O workloads can delay or starve RPC processing, resulting in increased latency, timeout events, and operational instability. Assigning 2 or more cores allows I/O and management tasks to run on separate reactors, improving responsiveness and operational stability. Accepts either hexadecimal CPU masks (for example, 0x3 or 0xff) or CPU list format (for example, 0-1,2,5). CPU lists are automatically converted to hexadecimal masks. The default value is 0x3.

  autoCleanupSnapshotAfterOnDemandBackupCompleted: ~
  # -- Setting that allows Longhorn to detect node failure and immediately migrate affected RWX volumes.
