The CSI-Addons project hosts extensions to the CSI specification
that provide advanced storage operations.
Network Fencing
The Network Fencing specification provides a
mechanism that Storage Providers can implement to network-fence any
client using corresponding CIDR blocks.
Reclaim Space
The Reclaim Space specification defines an extension
to the CSI Specification that will enable storage vendors (SP) to develop
controllers/plugins that can free unused storage allocations from existing
volumes.
Volume Replication
The Volume Replication specification provides a
mechanism that Storage Providers can implement to support async-replication
which can be used for disaster recovery operations.
