|Configure Eucalyptus Storage / Configure Block Storage|
This topic describes how to configure the local filesystem as the block storage backend provider for the Storage Controller (SC).
In this configuration the SC itself hosts the volume and snapshots for EBS and stores them as files on the local filesystem. It uses standard Linux iSCSI tools to serve the volumes to instances running on NCs.To configure overlay block storage for the zone, run the following commands on the CLC
euctl ZONE.storage.blockstoragemanager=overlayThe output of the command should be similar to:
euserv-describe-services --filter service-type=storage
Your local filesystem (overlay) backend is now ready to use with Eucalyptus.
