-The project's maintainers operate a live issue tracking dashboard for defects which they have under active triage and investigation. It can be accessed [here](https://mayadata.atlassian.net/secure/Dashboard.jspa?selectPageId=10015). You are strongly encouraged to familisarise yourself with the issues identified there before deploying Mayastor and/or raising issue reports.

+At a high-level, Mayastor consists of two major components.
### **Control plane:**
- * A single instance K8s controller which implements the [CSI](https://github.com/container-storage-interface/spec/blob/master/spec.md)
- controller spec but also private interfaces that otherwise would be implemented by your storage system. This is called Mother Of All Containers native storage or *MOAC* for short; it runs as a k8s deployment.
+ * A microservices patterned control plane, centered around a core agent which publically exposes a RESTful API. This is extended by a dedicated operator responsible
+ for managing the life cycle of "Mayastor Pools" (an abstraction for devices supplying the cluster with persistent backing storage) and a CSI compliant external provisioner (controller).
+ Source code for the control plane components is located in its [own repository](https://github.com/openebs/mayastor-control-plane)
* A _per_ node instance *mayastor-csi* plugin which implements the identity and node grpc services from CSI protocol.
### **Data plane:**
-* Each node you wish to use for storage or storage services will have to run a MayaStor daemon set. MayaStor itself has three major components: the Nexus, a local storage component, and the mayastor-csi plugin.

-# MOAC
-
-MOAC is a control plane of MayaStor. It is a NodeJS application written in
-javascript/typescript and makes use of kubernetes-client library to interact
-with K8s API server. In a nutshell it has following responsibilities:
-
-- _node operator_: keeps track of nodes with running MayaStor instances.
-- [pool operator](/doc/pool-operator.md): creates/updates/deletes storage pools on storage nodes as requested by admin by means of msp custom resources.
-- [volume operator](/doc/volume-operator.md): informs user about existing volumes on storage nodes by means of msv custom resources and allows simple modifications to them.
-- _CSI controller_: provisions volumes on storage nodes based on requests from k8s through CSI interface.
-
-## Requirements
-
-- required K8s version is 1.14 or newer
-- NodeJS v12 (instructions below)
-- Nix when building a docker image
-
-### NodeJS on Nix(OS)
-
-Enter a nix shell with NodeJS and python packages:
-
-```bash
-nix-shell -p nodejs-16_x python
-```
-
-### NodeJS on Ubuntu
-
-NodeJS v12 may not be available in default package repository on Ubuntu
-depending on Ubuntu release. If that's the case, new package source has to be
-added for NodeJS:
-
-```bash
-curl -sL https://deb.nodesource.com/setup_12.x -o nodesource_setup.sh
-sudo bash nodesource_setup.sh
-sudo apt install nodejs
-```
-
-## Build it
-
-Following command downloads and installs npm dependencies of moac and compiles
-ts files using typescript compiler:
-
-```bash
-npm install
-npm run compile
-```
-
-## Run it
-
-### Inside k8s cluster
-
-It is the most straightforward way to run moac. However also the least
-convenient for debugging issues. Use
-[k8s yaml file](/deploy/moac-deployment.yaml) for deploying MOAC to K8s cluster
-in usual way. This assumes that you are either fine with using the official
-docker image of MOAC or that you run your own private registry and you modified
-the deployment yaml file to use the private image instead.
-
-### Outside k8s cluster
-
-You can run MOAC without any K8s cluster with all components that are K8s
-specific disabled:
-
-```bash
-./index.js --skip-k8s
-```
-
-## Contributing
-
-1. Check your code style: `npm run check`
-2. Fix style errors that can be fixed: `npm run fix`
-3. Check that TS files compile: `npm run compile`
-4. All unit tests must pass: `npm run test`
-5. Clean generated JS files (optional): `npm run clean`
-
-## Updating the dependencies
-
-Updating npm dependencies in `package-lock.json` is not enough. In order to
-update dependencies in built docker images as well, the nix files need to be
-updated too;
-
-1. Update npm dependencies:
-
- ```bash
- npm update
- ```
-
- NOTE: If you want to update all packages to the very latest major versions
- that will likely include breaking API changes, then install
- `npm-check-updates` npm package and run `npm-check-updates -u` before the
- first step.
-
-2. If not already installed, install a `node2nix` tool which automates nix
- package creation for npm packages. On NixOS that can be done by following
- command:
-
- ```bash
- nix-env -f '' -iA nodePackages.node2nix
- ```
-
-3. Generate nix package build files. The flag `development` is needed for
- typescript to get included in the package, because it is in `devDependencies`
- (common case in JS world). The flag does not influence how things are built
- (debug info, code optimisations, etc.).
- ```bash
- rm -rf node_modules
- node2nix -l package-lock.json --development --nodejs-16 -c node-composition.nix
- ```
-
-4. Patch generated nix files by following patch in order to reduce the size
- of the package. This is a temporary workaround for
- https://github.com/svanderburg/node2nix/issues/187.

-
-## Building a Nix Package
-
-All Nix files generated by the `node2nix` tool are part of the repository so if
-you just want to build the package without changing or updating dependencies
-it is rather simple:
-
-1. Build the Nix MOAC package:
-
- ```bash
- nix-build default.nix -A package
- ```
-
-2. Run MOAC from the package:
- ```bash
- ./result/...
- ```
-
-## Architecture
-
-Unfortunately ASCII art is not good with colours. Left side of the picture
-is reserved for k8s cluster components. Up and right are MOAC components.
-Lines denote relations between all components.

-crucial for understanding what and when can happen with the volume. Imperfect
-approximation of FSA diagram for the volume follows:

-```
-
-## Troubleshooting
-
-Running moac with trace log level enabled (`-vv`) prints all details about
-incoming/outgoing CSI messages, watcher events, etc.
-
-## History
-
-The acronym MOAC comes from "Mother Of All Cases" (CAS means Container Attached
-Storage).
-
-## VSCode
-
-VSCode is a perfect choice for developing JS/TS projects. Remote docker plugin
-can be used to setup a dev environment for moac in a moment. Example of
-`.devcontainer.json` file:
-
-```json
-{
- "image": "node:16",
- "workspaceMount": "source=/path/to/repo/on/the/host/Mayastor,target=/workspace,type=bind,consistency=cached",
- "workspaceFolder": "/workspace",
- "extensions": [
- "chenxsan.vscode-standardjs"
- ]
-}
-```
-
-Note that this env is suitable for writing the code and running the tests but
-for building nix docker image you need nix package manager to be installed.

-// Volume operator managing volume k8s custom resources.
-//
-// Primary motivation for the resource is to provide information about
-// existing volumes. Other actions and their consequences follow:
-//
-// * destroying the resource implies volume destruction (not advisable)
-// * creating the resource implies volume import (not advisable)
-// * modification of "preferred nodes" property influences scheduling of new replicas
-// * modification of "required nodes" property moves the volume to different nodes
-// * modification of replica count property changes redundancy of the volume
-//
-// Volume operator stands between k8s custom resource (CR) describing desired
-// state and volume manager reflecting the actual state. It gets new/mod/del
-// events from both, from the world of ideas and from the world of material
-// things. It's task which is not easy, is to restore harmony between them:
-//
-// +---------+ new/mod/del +----------+ new/mod/del +-----------+
-// | Volumes +--------------> Operator <---------------+ Watcher |
-// +------^--+ ++--------++ +---^-------+

-// Unit tests for the pool operator
-//
-// Pool operator depends on a couple of modules:
-// * registry (real)
-// * node object (fake)
-// * pool object (fake)
-// * watcher (mocked)
-//
-// As you can see most of them must be fake in order to do detailed testing
-// of pool operator. That makes the code more complicated and less readable.

-# Pool Operator
-
-Pool operator is part of mayastor control plane (moac) and is responsible
-for storage pool creation and destruction on storage nodes. It follows classic
-k8s custom resource operator model. Custom resource (CR) managed by the operator
-is [MayastorPool](/csi/moac/crd/mayastorpool.yaml). CR objects represent the
-*desired state* by a user. Pool operator is responsible for making the desired
-state real. *Storage admin* creates and destroys mayastorpool CRs using
-`kubectl`. The operator issues create and destroy storage pool commands
-to storage nodes to make the state real.
-
-## MayastorPool
-
-MayastorPool custom resource is structured as follows:
-
-* metadata: Includes name of the pool which must be cluster-wide unique.
-* spec: Pool parameters including:
- * node: Name of the k8s node where the pool should be created (mayastor needs to be enabled on that node by means of node labels).
- * disks: Disk names (absolute paths to device files in /dev) which comprise the storage pool.
-* status:
- * state: State of the pool can be one of:
- * pending: Pool has not been created yet - either due to an error or because the k8s node does not have mayastor enabled.
- * online: Pool has been created and is healthy & usable.
- * degraded: Pool has been created and is usable but has some issue.
- * faulted: Pool has unrecoverable error and is not usable.
- * offline: Pool was created but currently it is not available because mayastor does not run on the k8s node.
- * reason: If applicable it provides additional information explaining the state.
-
-MayastorPool CR entries are shared between storage admin and pool operator
-with following responsibilities for each stake holder:
-
-* Storage admin:
- 1. Is responsible for creation/destruction of the CRs.
- 2. Modification of the CR is possible but not recommended.
- 3. Status section of the CR is read-only
-* Pool operator:
- 1. Is responsible for updating status section of the CR.
- 2. spec and metadata are read-only
- 3. Never creates or destroys any of the MayastorPool CRs.
-
-## List storage pools
-
-```bash
-kubectl get msp
-```
-
-## Create a storage pool
-
-Example of creating a storage pool `my-new-pool` on disk device
-`/dev/loop0` on k8s node `node1`:
