Shutting down IBM Spectrum Scale

Follow these steps to shut down IBM Spectrum Scale when using IBM Storage Enabler for Containers:

Ensure that all the containers that are using the IBM Spectrum Scale file systems that are being unmounted are moved to other nodes.
Ensure that the new pods that are using the IBM Spectrum Scale file systems that are being unmounted are not scheduled on the node.
Stop Kubernetes and Docker.

Shutdown the IBM Spectrum Scale file system using the mmshutdown command.

Note: Stop all PODs manually before running the mmshutdown command. Otherwise, a worker node might crash. If a crash occurs, its recovery involves recovery of the node, followed by manually stopping all PODs before resuming any prior shutdown.

For more information on the mmshutdown command, see the IBM Spectrum Scale: Command and Programming Reference guide in the IBM Spectrum Scale Knowledge Center.
