Shutting Down a Storage Cluster

A shutdown suspends the entire storage cluster. The backend shutdown API is called by the Simplyblock Operator, which then polls until the cluster reports suspended.

Shutting down the storage cluster

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

How the request is executed, tracked, and cleared is described in Storage Cluster Actions. A suspended cluster is brought back with Starting a Storage Cluster.

Warning

A cluster shutdown takes every volume of the cluster offline. Workloads consuming those volumes lose their storage for the duration of the shutdown. To take a single storage node out of service instead, see Shutting Down a Storage Node.
