HwameiStor is an HA local storage system for cloud-native stateful workloads. It creates a local storage resource pool for centrally managing all disks such as HDD, SSD, and NVMe. It uses the CSI architecture to provide distributed services with local volumes and provides data persistence capabilities for stateful cloud-native workloads or components.
HwameiStor is a cloud-native storage project listed in CNCF Landscape, with capabilities to support for your production environment.
At present, HwameiStor is still in the alpha stage.

HwameiStor contains several modules:
local-disk-manager (LDM) is designed to hold the management of disks on nodes. Other modules such as local-storage can take advantage of the disk management feature provided by LDM. Learn more
local-storage (LS) provides a cloud-native local storage system. It aims to provision high-performance persistent LVM volume with local access to applications. Learn more
Scheduler is to automatically schedule a pod to a correct node which has the associated HwameiStor volumes. Learn more
admission-controller is a webhook that can automatically determine which pod uses the HwameiStor volume and, help to modify the schedulerName to hwameistor-scheduler. Learn more
Evictor is used to automatically migrate HwameiStor volumes in case of node or pod eviction. When a node or pod is evicted as either Planned or Unplanned, the associated HwameiStor volumes, which have a replica on the node, will be detected and migrated out this node automatically. Learn more
DRBD (Distributed Replicated Block Device) is composed of Linux kernel modules and related scripts to build high available clusters. It is implemented by mirroring the entire device over the network, which can be thought of as a kind of network RAID. This installer can directly install DRBD to a container cluster. Currently this module is only for testing purposes. Learn more
