Document the design for expand cluster workflow
shtripat opened this issue · comments
The existing cluster's storage capacity could be increased by getting more new storage devices in to existing cluster nodes or new nodes itself with set of storage devices.
Document should clearly articulate the flow and like -
- How the additional hardware (be it new device in existing node or a fresh node itself) is discivered in tendrl
- How admin can select and decide what to be done with the new devices (storage profiles etc to be decided or in case of gluster say where this disk fits and a brick gets added)
- Trigger the expansion of cluster with new set of devices and async task start
