 ### Error Scheme
 
 All CSI API calls defined in this spec MUST return a [standard gRPC status](https://github.com/grpc/grpc/blob/master/src/proto/grpc/status/status.proto).
 Most gRPC libraries provide helper methods to set and read the status fields.
 
-The status `code` MUST contain a [canonical error code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go). COs must handle all valid error codes. Each RPC defines a set of gRPC error codes that MUST be returned by the plugin when specified conditions are encountered. In addition to those, if the conditions defined below are encountered, the plugin MUST return the associated gRPC error code.

In addition to those, if the conditions defined below are encountered, the plugin MUST return the associated gRPC error code.

+| Missing required field | 3 INVALID_ARGUMENT | Indicates that a required field is missing from the request. More human-readable information MAY be provided in the `status.message` field. | Caller MUST fix the request by adding the missing required field before retrying. |
 | Invalid or unsupported field in the request | 3 INVALID_ARGUMENT | Indicates that the one ore more fields in this field is either not allowed by the Plugin or has an invalid value. More human-readable information MAY be provided in the gRPC `status.message` field. | Caller MUST fix the field before retrying. |
+| Permission denied | 7 PERMISSION_DENIED | The Plugin is able to derive or otherwise infer an identity from the secrets present within an RPC, but that identity does not have permission to invoke the RPC. | System administrator SHOULD ensure that requisite permissions are granted, after which point the caller MAY retry the attempted RPC. |
+| Operation pending for volume | 10 ABORTED | Indicates that there is already an operation pending for the specified volume. In general the Cluster Orchestrator (CO) is responsible for ensuring that there is no more than one call "in-flight" per volume at a given time. However, in some circumstances, the CO MAY lose state (for example when the CO crashes and restarts), and MAY issue multiple calls simultaneously for the same volume. The Plugin, SHOULD handle this as gracefully as possible, and MAY return this error code to reject secondary calls. | Caller SHOULD ensure that there are no other calls pending for the specified volume, and then retry with exponential back off. |
+| Call not implemented | 12 UNIMPLEMENTED | The invoked RPC is not implemented by the Plugin or disabled in the Plugin's current mode of operation. | Caller MUST NOT retry. Caller MAY call `GetPluginCapabilities`, `ControllerGetCapabilities`, or `NodeGetCapabilities` to discover Plugin capabilities. |
+| Not authenticated | 16 UNAUTHENTICATED | The invoked RPC does not carry secrets that are valid for authentication. | Caller SHALL either fix the secrets provided in the RPC, or otherwise regalvanize said secrets such that they will pass authentication by the Plugin for the attempted RPC, after which point the caller MAY retry the attempted RPC. |
 
 The status `message` MUST contain a human readable description of error, if the status `code` is not `OK`.
 This string MAY be surfaced by CO to end users.
 
-The status `details` MUST be empty. In the future, this spec may require `details` to return a machine-parsable protobuf message if the status `code` is not `OK` to enable CO's to implement smarter error handling and fault resolution.

 Reverting a snapshot, where data in the original volume is erased and replaced with data in the snapshot, is an advanced functionality not every storage system can support and therefore is currently out of scope.
 
+##### The ready_to_use Parameter
+
+Some SPs MAY "process" the snapshot after the snapshot is cut, for example, maybe uploading the snapshot somewhere after the snapshot is cut.
+The post-cut process MAY be a long process that could take hours.
+The CO MAY freeze the application using the source volume before taking the snapshot.
+The purpose of `freeze` is to ensure the application data is in consistent state.
+When `freeze` is performed, the container is paused and the application is also paused.
+When `thaw` is performed, the container and the application start running again.
+During the snapshot processing phase, since the snapshot is already cut, a `thaw` operation can be performed so application can start running without waiting for the process to complete.
+The `ready_to_use` parameter of the snapshot will become `true` after the process is complete.
+
+For SPs that do not do additional processing after cut, the `ready_to_use` parameter SHOULD be `true` after the snapshot is cut.
+`thaw` can be done when the `ready_to_use` parameter is `true` in this case.
+
+The `ready_to_use` parameter provides guidance to the CO on when it can "thaw" the application in the process of snapshotting.
+If the cloud provider or storage system needs to process the snapshot after the snapshot is cut, the `ready_to_use` parameter returned by CreateSnapshot SHALL be `false`.
+CO MAY continue to call CreateSnapshot while waiting for the process to complete until `ready_to_use` becomes `true`.
+Note that CreateSnapshot no longer blocks after the snapshot is cut.
+
+A gRPC error code SHALL be returned if an error occurs during any stage of the snapshotting process.
+A CO SHOULD explicitly delete snapshots when an error occurs.
+
+Based on this information, CO can issue repeated (idemponent) calls to CreateSnapshot, monitor the response, and make decisions.
+Note that CreateSnapshot is a synchronous call and it MUST block until the snapshot is cut.

 It is NOT REQUIRED for a controller plugin to implement the `LIST_SNAPSHOTS` capability if it supports the `CREATE_DELETE_SNAPSHOT` capability: the onus is upon the CO to take into consideration the full range of plugin capabilities before deciding how to proceed in the above scenario.
-A controller plugin COULD implement the `LIST_SNAPSHOTS` capability and call it repeatedly with the `snapshot_id` as a filter to query whether the uploading process is complete or not if it needs to upload a snapshot after it is being cut.
 
-##### Snapshot Statuses
-
-A snapshot could have the following statusus: UPLOADING, READY, and ERROR.
-
-Some cloud providers will upload the snapshot to a location in the cloud (i.e., an object store) after the snapshot is cut.
-Uploading may be a long process that could take hours.
-If a `freeze` operation was done on the application before taking the snapshot, it could be a long time before the application can be running again if we wait until the upload is complete to `thaw` the application.
-The purpose of `freeze` is to ensure the application data is in consistent state.
-When `freeze` is performed, the container is paused and the application is also paused.
-When `thaw` is performed, the container and the application start running again.
-During the snapshot uploading phase, since the snapshot is already cut, a `thaw` operation can be performed so application can start running without waiting for the upload to complete.
-The status of the snapshot will become `READY` after the upload is complete.
-
-For cloud providers and storage systems that don't have the uploading process, the status should be `READY` after the snapshot is cut.
-`thaw` can be done when the status is `READY` in this case.
-
-A `CREATING` status is not included here because CreateSnapshot is synchronous and will block until the snapshot is cut.
-
-`ERROR` is a terminal snapshot status.
-A CO SHOULD explicitly delete snapshots in this status.
-
-The SnapshotStatus parameter provides guidance to the CO on what action can be taken in the process of snapshotting.
-Based on this information, CO can issue repeated (idemponent) calls to CreateSnapshot, monitor the response, and make decisions.
-Note that CreateSnapshot is a synchronous call and it must block until the snapshot is cut.
-If the cloud provider or storage system does not need to upload the snapshot after it is cut, the status returned by CreateSnapshot SHALL be `READY`.
-If the cloud provider or storage system needs to upload the snapshot after the snapshot is cut, the status returned by CreateSnapshot SHALL be `UPLOADING`.
-CO MAY continue to call CreateSnapshot while waiting for the upload to complete until the status becomes `READY`.
-Note that CreateSnapshot no longer blocks after the snapshot is cut.
-
-Alternatively, ListSnapshots can be called repeatedly with snapshot_id as filtering to wait for the upload to complete.
 ListSnapshots SHALL return with current information regarding the snapshots on the storage system.
-When upload is complete, the status of the snapshot from ListSnapshots SHALL become `READY`.
+When processing is complete, the `ready_to_use` parameter of the snapshot from ListSnapshots SHALL become `true`.
+The downside of calling ListSnapshots is that ListSnapshots will not return a gRPC error code if an error occurs during the processing. So calling CreateSnapshot repeatedly is the preferred way to check if the processing is complete.

 # Mock CSI Driver
-Extremely simple mock driver used to test `csi-sanity` based on `rexray/gocsi/mock`
+Extremely simple mock driver used to test `csi-sanity` based on `rexray/gocsi/mock`.
+It can be used for testing of Container Orchestrators that implement client side
+of CSI interface.
+
+```
+Usage of mock:
+  -disable-attach
+        Disables RPC_PUBLISH_UNPUBLISH_VOLUME capability.
+  -name string
+        CSI driver name. (default "io.kubernetes.storage.mock")
+```
+
+It prints all received CSI messages to stdout encoded as json, so a test can check that
+CO sent the right CSI message.
+
+Example of such output:
+
+```

 ### Running in a statefulset
 
-It is necessary to create a new service account and give it enough privileges to run the snapshotter. We provide one omnipotent yaml file that creates everything that's necessary, however it should be split into multiple files in production.
+It is necessary to create a new service account and give it enough privileges to run the snapshotter. We provide .yaml files that deploy for use together with the hostpath example driver. A real production deployment must customize them:
 
 ```
-$ kubectl create deploy/kubernetes/statefulset.yaml
+$ for i in $(find deploy/kubernetes -name '*.yaml'); do kubectl create -f $i; done
 ```
