Activating a Storage Cluster

Activation makes a storage cluster serve I/O for the first time. It is normally automatic: a cluster is activated by the Simplyblock Operator once every storage node declared in its StorageNodeSet is online and healthy, and the number of those nodes is at least the sum of the data chunks, the parity chunks, and one. See Create a Storage Cluster for the conditions in detail.

The activate action exists for the case where that did not happen, for example, because nodes came online after the automatic check had already passed.

Activating a cluster manually

kubectl patch storagecluster simplyblock-cluster -n simplyblock \
    --type=merge -p '{"spec": {"action": "activate"}}'

The action succeeds once the cluster reports the status active. How the request is executed, tracked, and cleared is described in Storage Cluster Actions.

Warning

A StorageCluster that is deleted while spec.action is activate has its finalizer removed without the backend cluster being deleted. The cluster is then left behind on the control plane and has to be removed there. Clear spec.action before deleting the resource.
