OpenEBS is the leading open-source project for container-attached and container-native storage on Kubernetes. OpenEBS adopts Container Attached Storage (CAS) approach, where each workload is provided with a dedicated storage controller. OpenEBS implements granular storage policies and isolation that enable users to optimize storage for each specific workload. OpenEBS runs in user space and does not have any Linux kernel module dependencies. See OpenEBS Features & Benefits and Use cases.
OpenEBS requires iSCSI client to be configured and iscsid service running on the host nodes. Verify if iSCSI service is up and running before starting the installation.
