Unload

If the RAID is not needed at the moment, you can unloaded unload it using the command:

xnr_cli raid unload --name xnraid

The unload operation switches the RAID to the Offline state, starts to reject new incoming IO requests, waits for outstanding IO completion, gracefully interrupts internal services such as initialization and reconstruction, clears the auto-start flag and stops the RAID. The Stopped RAID is not reported by the “raid show” command. Although, it is configured (persisted in the configuration database), it is not automatically restarted if the engine or the server is restarted.

In a high-availability (HA) configuration (not supported by this release), it is safe to unload the RAID at one node and restore it and start IO at another node. A RAID can be in Stopped state on multiple nodes but must not be running (Operational or Failed) at more than one node simultaneously to avoid split-brain situation and potential data corruption.
