c9943320ac cephfs: skip NetNamespaceFilePath if the volume is pre-provisioned
In case of pre-provisioned volume the clusterID is
not set in the volume context as the clusterID is missing
we cannot extract the NetNamespaceFilePath from the
configuration file. For static volume and dynamically
provisioned volume the clusterID is set.

Note:- This is a special case to support mounting PV
without clusterID parameter.

70674565df rbd: consider rbd as default mounter if not set
For the default mounter the mounter option
will not be set in the storageclass and as it is
not available in the storageclass same will not
be set in the volume context, Because of this the
mapOptions are getting discarded. If the mounter
is not set assuming it's an rbd mounter.

Note:- If the mounter is not set in the storageclass
we can set it in the volume context explicitly,
Doing this check-in node server to support backward
existing volumes and the check is minimal we are not
altering the volume context.

The added extra 1 minute is useful though to avoid
multiple calls to complete the rollback and in

6d83df9cc9 nfs: add basic provisioner with create/delete procedures
These NFS Controller and Identity servers are the base for the new
provisioner. The functionality is currently extremely limited, follow-up
PRs will implement various CSI procedures.

CreateVolume is implemented with the bare minimum. This makes it
possible to create a volume, and mount it with the
kubernetes-csi/csi-driver-nfs NodePlugin.

DeleteVolume unexports the volume from the Ceph managed NFS-Ganesha
service. In case the Ceph cluster provides multiple NFS-Ganesha
deployments, things might not work as expected. This is going to be
addressed in follow-up improvements.

Lots of TODO comments need to be resolved before this can be declared
"production ready". Unit- and e2e-tests are missing as well.

  hard & soft limit is reduced by 2 to account for depth that
  will be added by temp & final clone.

- If the data source is a Snapshot, the underlying image is
  itself flattened.
  hard & soft limit is reduced by 1 to account for depth that
  will be added by the clone which will be restored from the
  snapshot.

Flattening step for resulting PVC image restored from snapshot is removed.
Flattening step for temp clone & final image is removed when pvc clone is

4f0bb2315b rbd: add aws-sts-metdata encryption type
With Amazon STS and kubernetes cluster is configured with
OIDC identity provider, credentials to access Amazon KMS
can be fetched using oidc-token(serviceaccount token).
Each tenant/namespace needs to create a secret with aws region,
role and CMK ARN.
Ceph-CSI will assume the given role with oidc token and access
aws KMS, with given CMK to encrypt/decrypt DEK which will stored
in the image metdata.

3eb0fa5e21 rbd: fix parsing mapOptions
Currently, we support

mapOption: "krbd:v1,v2,v3;nbd:v1,v2,v3"

- By omitting `krbd:` or `nbd:`, the option(s) apply to
  rbdDefaultMounter which is krbd.
- A user can _override_ the options for a mounter by specifying `krbd:`
  or `nbd:`.
  mapOption: "v1,v2,v3;nbd:v1,v2,v3"
  is effectively the same as the 1st example.
- Sections are split by `;`.
- If users want to specify common options for both `krbd` and `nbd`,
  they should mention them twice.

But in case if the krbd or nbd specifc options contian `:` within them,
then the parsing is failing now.

GRPC error: badly formatted map/unmap options:
"krbd:read_from_replica=localize,crush_location=zone:zone1;"

This patch fix the above case where the options itself contain `:`
delimitor
ex: krbd:v1,v2,v3=v31:v32;nbd:v1,v2,v3"

Please note, if you are using such options which contain `:` delimiter,
then it is mandatory to specify the mounter-type.

Mounts managed by ceph-fuse may get corrupted by e.g. the ceph-fuse process
exiting abruptly, or its parent container being terminated, taking down its
child processes with it.

This commit adds checks to NodeStageVolume and NodePublishVolume procedures
to detect whether a mountpoint in staging_target_path and/or target_path is
corrupted, and remount is performed if corruption is detected.

* Code for building store.VolumeOptions is factored out into a separate function.

* Changed args of getCredentailsForVolume() and NodeServer.mount() so that
  instead of passing in whole csi.NodeStageVolumeRequest, only necessary

1f012004a6 util: configure tenants vaultAuthNamespace if not set
When a tenant provides a configuration that includes the
`vaultNamespace` option, the `vaultAuthNamespace` option is still taken
from the global configuration. This is not wanted in all cases, as the
`vaultAuthNamespace` option defauls to the `vaultNamespace` option which
the tenant may want to override as well.

The following behaviour is now better defined:

1. no `vaultAuthNamespace` in the global configuration:
   A tenant can override the `vaultNamespace` option and that will also
   set the `vaultAuthNamespace` option to the same value.

2. `vaultAuthNamespace` and `vaultNamespace` in the global configuration:
   When both options are set to different values in the global
   configuration, the tenant `vaultNamespace` option will not override
   the global `vaultAuthNamespace` option. The tenant can configure
   `vaultAuthNamespace` with a different value if required.

f6894909d7 util: use vaultNamespace if vaultAuthNamespace is not set
When a tenant configures `vaultNamespace` in their own ConfigMap, it is
not applied to the Vault configuration, unless `vaultAuthNamespace` is
set as well. This is unexpected, as the `vaultAuthNamespace` usually is
something configured globally, and not per tenant.

The `vaultAuthNamespace` is an advanced option, that is often not needed
to be configured. Only when tenants have to configure their own
`vaultNamespace`, it is possible that they need to use a different
`vaultAuthNamespace`. The default for the `vaultAuthNamespace` is now
the `vaultNamespace` value from the global configuration. Tenants can
still set it to something else in their own ConfigMap if needed.

Note that Hashicorp Vault Namespaces are only functional in the
Enterprise version of the product. Therefor this can not be tested in
the Ceph-CSI e2e with the Open Source version of Vault.

SINGLE_NODE_WRITER capability ambiguity has been fixed in csi spec v1.5
which allows the SP drivers to declare more granular WRITE capability in form
of SINGLE_NODE_SINGLE_WRITER or SINGLE_NODE_MULTI_WRITER.

These are not really new capabilities rather capabilities introduced to
get the desired functionality from CO side based on the capabilities SP
driver support for various CSI operations, this new capabilities also help
to address new access mode RWOP (readwriteoncepod).

This commit adds a helper function which identity the request is of
multiwriter mode and also validates whether it is filesystem mode or
block mode. Based on the inspection it fails to allow multi write
requests for filesystem mode and only allow multi write request against
block mode.

This commit also adds unit tests for isMultiWriterBlock function which
validates various accesstypes and accessmodes.

5aa1e4d225 rbd: change the configmap of HPCS/KP key names to reflect the IBM string
considering IBM has different crypto services (ex: SKLM) in place, its
good to keep the configmap key names with below format

`IBM_KP_...` instead of `KP_..`

so that in future, if we add more crypto services from IBM we can keep
similar schema specific to that specific service from IBM.

Ex: `IBM_SKLM_...`

203920d8f4 rbd: move driver component into the rbd/driver package
The rbd package contains several functions that can be used by
CSI-Addons Service implmentations. Unfortunately it is not possible to
do this, as the rbd-driver needs to import the csi-addons/rbd package to
provide the CSI-Addons server. This causes a circular import when
services use the rbd package:

 - rbd/driver.go import csi-addons/rbd
 - csi-addons/rbd import rbd (including the driver)

By moving rbd/driver.go into its own package, the circular import can be
prevented.

image which is sent in EnableVolumeReplication request
if the actual rbd image size is 1TiB we are creating
a dummy image of 1TiB which is not good. even though
its a thin provisioned rbd images this is causing
issue for the transfer of the snapshot during

of an image is available.

Mirroring when configured in journal mode, mirroring will
utilize the RBD journaling image feature to replicate the image

bdcf3273b5 rbd: provide a way to supply mounter specific mapOptions from sc
Uses the below schema to supply mounter specific map/unmapOptions to the
nodeplugin based on the discussion we all had at
https://github.com/ceph/ceph-csi/pull/2636

This should specifically be really helpful with the `tryOthermonters`
set to true, i.e with fallback mechanism settings turned ON.

mapOption: "kbrd:v1,v2,v3;nbd:v1,v2,v3"

- By omitting `krbd:` or `nbd:`, the option(s) apply to
  rbdDefaultMounter which is krbd.
- A user can _override_ the options for a mounter by specifying `krbd:`
  or `nbd:`.
  mapOption: "v1,v2,v3;nbd:v1,v2,v3"
  is effectively the same as the 1st example.
- Sections are split by `;`.
- If users want to specify common options for both `krbd` and `nbd`,
  they should mention them twice.

517ad8c644 rbd: use dummy image to workaround rbd scheduling bug
currently we have a bug in rbd mirror scheduling module.
After doing failover and failback the scheduling is not
getting updated and the mirroring snapshots are not
getting created periodically as per the scheduling
interval. This PR workarounds this one by doing below
operations

* Create a dummy (unique) image per cluster and this image
should be easily identified.

* During Promote operation on any image enable the
mirroring on the dummy image. when we enable the mirroring
on the dummy image the pool will get updated and the
scheduling will be reconfigured.

* During Demote operation on any image disable the mirroring
on the dummy image. the disable need to be done to enable
the mirroring again when we get the promote request to make
the image as primary

* When the DR is no more needed, this image need to be
manually cleanup as for now as we dont want to add a check
in the existing DeleteVolume code path for delete dummy image
as it impact the performance of the DeleteVolume workflow.

7e22180125 rbd: call undoStagingTransaction() when NodeStageVolume() fails
On line 341 a `transaction` is created. This is passed to the deferred
`undoStagingTransaction()` function when an error in the
`NodeStageVolume` procedure is detected. So far, so good.

However, on line 356 a new `transaction` is returned. This new
`transaction` is not used for the defer call.

By removing the empty `transaction` that is used in the defer call, and
calling `undoStagingTransaction()` on an error of `stageTransaction()`,
the code is a little simpler, and the cleanup of the transaction should
be done correctly now.

3686b6da8b rbd: utilize cookie support from rbd for nbd
Problem:
On remap/attach of device (i.e. nodeplugin restart), there is no way
for rbd-nbd to defend if the backend storage is matching with the initial
backend storage.

Say, if an initial map request for backend "pool1/image1" got mapped to
/dev/nbd0 and the userspace process is terminated (on nodeplugin restart).
A next remap/attach (nodeplugin start) request within reattach-timeout is
allowed to use /dev/nbd0 for a different backend "pool1/image2"

For example, an operation like below could be dangerous:

$ sudo rbd-nbd map --try-netlink rbd-pool/ext4-image
/dev/nbd0
$ sudo blkid /dev/nbd0
/dev/nbd0: UUID="bfc444b4-64b1-418f-8b36-6e0d170cfc04" TYPE="ext4"
$ sudo pkill -15 rbd-nbd   <-- nodeplugin terminate
$ sudo rbd-nbd attach --try-netlink --device /dev/nbd0 rbd-pool/xfs-image
/dev/nbd0
$ sudo blkid /dev/nbd0
/dev/nbd0: UUID="d29bf343-6570-4069-a9ea-2fa156ced908" TYPE="xfs"

Solution:
rbd-nbd/kernel now provides a way to keep some metadata in sysfs to identify
between the device and the backend, so that when a remap/attach request is
made, rbd-nbd can compare and avoid such dangerous operations.

With the provided solution, as part of the initial map request, backend
cookie (ceph-csi VOLID) can be stored in the sysfs per device config, so
that on a remap/attach request rbd-nbd will check and validate if the
backend per device cookie matches with the initial map backend with the help
of cookie.

At Ceph-csi we use VOLID as device cookie, which will be unique, we pass
the VOLID as cookie at map and use the same at the time of attach, that
way rbd-nbd can identify backends and their matching devices.

much possible that the cluster is heterogeneous i.e. the PV creation and
application container might both be on different nodes with different
kernel versions (krbd driver versions).

This PR adds a mechanism to check for the supported krbd features during
mount time, if the krbd driver doesn't have the specified image feature
then it will fall back to rbd-nbd mounter.

c852f487a5 util: set defaults for Vault config before converting
When using UPPER_CASE formatting for the HashiCorp Vault KMS
configuration, a missing `VAULT_DESTROY_KEYS` will cause the option to
be set to "false". The default for the option is intended for be "true".

This is a difference in behaviour between the `vaultDestroyKeys` and
`VAULT_DESTROY_KEYS` options. Both should use a default of "true" when
the configuration does not set the option explicitly.

By setting the default options in the `standardVault` struct before
unmarshalling the configuration in it, the default values will be
retained for the missing configuration options.

b49bf4b987 rbd: parse migration secret and set it for controller server operations
This commit adds a couple of helper functions to parse the migration
request secret and set it for further csi driver operations.

More details:

The intree secret has a data field called "key" which is the base64
admin secret key. The ceph CSI driver currently expect the secret to
contain data field "UserKey" for the equivalant. The CSI driver also
expect the "UserID" field which is not available in the in-tree secret
by deafult. This missing userID will be filled (if the username differ
than 'admin') in the migration secret as 'adminId' field in the
migration request, this commit adds the logic to parse this migration
secret as below:

"key" field value will be picked up from the migraion secret to "UserKey"
field.
"adminId" field value will be picked up from the migration secret to "UserID"
field

if `adminId` field is nil or not set, `UserID` field will be filled with
default value ie `admin`.The above logic get activated only when the secret
is a migration secret, otherwise skipped to the normal workflow as we have
today.

b132696e54 rbd: note that thick-provisioning is deprecated
Thick-provisioning was introduced to make accounting of assigned space
for volumes easier. When thick-provisioned volumes are the only consumer
of the Ceph cluster, this works fine. However, it is unlikely that this
is the case. Instead, accounting of the requested (thin-provisioned)
size of volumes is much more practical as different types of volumes can
be tracked.

OpenShift already provides cluster-wide quotas, which can combine
accounting of requested volumes by grouping different StorageClasses.

In addition to the difficult practise of allowing only thick-provisioned
RBD backed volumes, the performance makes thick-provisioning
troublesome. As volumes need to be completely allocated, data needs to
be written to the volume. This can take a long time, depending on the
size of the volume. Provisioning, cloning and snapshotting becomes very
much noticeable, and because of the additional time consumption, more
prone to failures.

If the user resizes the image on the ceph cluster.
User cannot not automatically resize the filesystem
created on the rbd image. Even if deletes and
recreates the kubernetes objects, the new size
will not be visible on the node.

With this changes During the NodeStageVolumeRequest
the nodeplugin will check the size of the mapped rbd
image on the node using the devicePath. and also
the rbd image size on the ceph cluster.

If the size is not matching it will do the file
system resize on the node as part of the
NodeStageVolumeRequest RPC call.

The user need to do below operation to see new size
* Resize the rbd image in ceph cluster
* Scale down all the application pods using the static
PVC.
* Make sure no application pods which are using the
static PVC is running on a node.
* Scale up all the application pods.

the migration nodestage request does not carry the 'clusterID' in it
and only monitors are available with the volumeContext. The volume
context flag 'migration=true' and 'static=true' flags allow us to
fill 'clusterID' from the passed in monitors to the volume Context,so
that rest of the static operations on nodestage can be proceeded as we
do treat static volumes today.

1f5963919f util: get clusterID for the passed in mon string
as part of migration support, the clusterID has to be fetched
from passed in mon. Because the intree RBD storage class only
got monitor and not `clusterID` parameter support. However, in
CSI, SC has the `clusterID` parameter support but not mon. Due
to that we have to fetch the clusterID from config file for the
passed in mon and use it in our operations. This adds a helper
function to retrieve clusterID from passed in mon string.

c9cc36d8db rbd: provide alternatives to preserve the ceph log files
Currently, we delete the ceph client log file on unmap/detach.

This patch provides additional alternatives for users who would like to
persist the log files.

Strategies:
-----------
`remove`: delete log file on unmap/detach
`compress`: compress the log file to gzip on unmap/detach
`preserve`: preserve the log file in text format

Note that the default strategy will be remove on unmap, and these options
can be tweaked from the storage class

Compression size details example:

On Map: (with debug-rbd=20)
---------
$ ls -lh
-rw-r--r-- 1 root root 526K Sep  1 18:15

We also return a !ready just post issuing a resync.

The change is to ensure we return errors in these

return !ready with nil errors.

This commit adds capability to genVolFromVolumeOptions() to fetch
mapped clusted-id & mon ips for mirrored PVC on secondary cluster
which may have different cluster-id.

This is required for NodeStageVolume().

We also don't need to check for mapping during volume create requests,
so it can be disabled by passing a bool checkClusterIDMapping as false.

GetMonsAndClusterID() is modified to accept bool checkClusterIDMapping
based on which clustermapping is checked to fetch mapped cluster-id and

Because of the name of the package "kms", the types, functions and

By splitting the public GetClusterMappingInfo() function into an

use different files for each go-routine, and testing becomes more

4f40213d8e rbd: fix rbd-nbd io-timeout to never abort
With the tests at CI, it kind of looks like that the IO is timing out after
30 seconds (default with rbd-nbd). Since we have tweaked reattach-timeout
to 300 seconds at ceph-csi, we need to explicitly set io-timeout on the
device too, as it doesn't make any sense to keep
io-timeout < reattach-timeout

Hence we set io-timeout for rbd nbd to 0. Specifying io-timeout 0 tells
the nbd driver to not abort the request and instead see if it can be
restarted on another socket.

With the new `vaultDestroyKeys` configuration parameter, this behaviour

-b0285c97-a0ce-11eb-8c66-0242ac110002`
contains the `site1-storage` as the clusterID,
now Ceph-CSI will look for the corresponding
clusterID `site2-storage` from the above configmap.
If the clusterID mapping is found now Ceph-CSI
will look for the poolID mapping ie mapping between
`1` and `2`. Example:- pool with name exists on
both the clusters with different ID's Replicapool
with ID `1` on site1 and Replicapool with ID `2`
on site2. After getting the required mapping Ceph-CSI
has the required information to get more details
from the rados OMAP. If we have multiple clusterID mapping
it will loop through all the mapping and checks the
corresponding pool to get the OMAP data. If the clusterID
mapping does not exist Ceph-CSI will return an `Not Found`

f2d5c2e0df util: add vaultAuthNamespace option for Vault KMS
The new `vaultAuthNamespace` configuration parameter can be set to the
Vault Namespace where the authentication is setup in the service. Some
Hashicorp Vault deployments use sub-namespaces for their users/tenants,
with a 'root' namespace where the authentication is configured. This
requires passing of different Vault namespaces for different operations.

Example:
 - the Kubernetes Auth mechanism is configured for in the Vault
   Namespace called 'devops'
 - a user/tenant has a sub-namespace called 'devops/website' where the
   encryption passphrases can be placed in the key-value store

The configuration for this, then looks like:

    vaultAuthNamespace: devops
    vaultNamespace: devops/homepage

Note that Vault Namespaces are a feature of the Hashicorp Vault
Enterprise product, and not part of the Open Source version. This
prevents adding e2e tests that validate the Vault Namespace
configuration.

As a result, the below error is reported:

526ff95f10 rbd: add support to expand encrypted volume
Previously in ControllerExpandVolume() we had a check for encrypted
volumes and we use to fail for all expand requests on an encrypted
volume. Also for Block VolumeMode PVCs NodeExpandVolume used to be
ignored/skipped.

With these changes, we add support for the expansion of encrypted volumes.
Also for raw Block VolumeMode PVCs with Encryption we call NodeExpandVolume.

That said,
With LUKS1, cryptsetup utility doesn't prompt for a passphrase on resizing
the crypto mapper device. This is because LUKS1 devices don't use kernel
keyring for volume keys.

Whereas, LUKS2 devices use kernel keyring for volume key by default, i.e.
cryptsetup utility asks for a passphrase if it detects volume key was
previously passed to dm-crypt via kernel keyring service, we are overriding
the default by --disable-keyring option during cryptsetup open command.
So that at the time of crypto mapper device resize we will not be
prompted for any passphrase.

b6a88dd728 rbd: add volume healer
Problem:
-------
For rbd nbd userspace mounter backends, after a restart of the nodeplugin
all the mounts will start seeing IO errors. This is because, for rbd-nbd
backends there will be a userspace mount daemon running per volume, post
restart of the nodeplugin pod, there is no way to restore the daemons
back to life.

Solution:
--------
The volume healer is a one-time activity that is triggered at the startup
time of the rbd nodeplugin. It navigates through the list of volume
attachments on the node and acts accordingly.

For now, it is limited to nbd type storage only, but it is flexible and
can be extended in the future for other backend types as needed.

From a few feets above:
This solves a severe problem for nbd backed csi volumes. The healer while
going through the list of volume attachments on the node, if finds the
volume is in attached state and is of type nbd, then it will attempt to
fix the rbd-nbd volumes by sending a NodeStageVolume request with the
required volume attributes like secrets, device name, image attributes,
and etc.. which will finally help start the required rbd-nbd daemons in
the nodeplugin csi-rbdplugin container. This will allow reattaching the
backend images with the right nbd device, thus allowing the applications
to perform IO without any interruptions even after a nodeplugin restart.

d941e5abac util: make parseTenantConfig() usable for modular KMSs
parseTenantConfig() only allowed configuring a defined set of options,
and KMSs were not able to re-use the implementation. Now, the function
parses the ConfigMap from the Tenants Namespace and returns a map with
options that the KMS supports.

The map that parseTenantConfig() returns can be inspected by the KMS,
and applied to the vaultTenantConnection type by calling parseConfig().

095a82f37d util: returns actual error instead of ErrPoolNotFound
This commit returns actual error returned by the go-ceph API
to the function GetPoolName(..) instead of just returning
ErrPoolNotFound everytime there is error getting the pool id.
There is a issue reported in which the snapshot creation
takes much more time to reach True state
(i.e., between 2-7 mins) and keeps trying to create with
below error though pool is present:
rpc error: code = NotFound desc = pool not found: pool ID (21)
not found in Ceph cluster.

Since we cannot interpret the actual error for the delay in
snapshot creation, it is required to return the actual error
as well so that we can uderstand the reason.

the seperator, you get an array with one empty string.  This results
in volumes failing to mount with "invalid feature " (note extra space
because it's trying to check if 'empty string' is a valid feature).

This patch checks if the string is empty, and if so, it just decides
to skip the entire validation and returning nothing.

25d0a1cfc0 rbd: add support for block-devices in NodeGetVolumeStats()
The NodeGetVolumeStats procedure can now be used to fetch the capacity
of the RBD block-device. By default this is a thin-provisioned device,
which means that the capacity is not reserved in the Ceph cluster. This
makes it possible to over-provision the cluster.

In order to detect the amount of storage used by the RBD block-device
(when thin-provisioned), it is required to connect to the Ceph cluster.
Unfortunately, the NodeGetVolumeStats CSI procedure does not provide
enough parameters to connect to the Ceph cluster and fetch more details
about the RBD image.

52290333e6 rbd: modified logic to check image watchers
Before RBD map operation, we do check the
watchers on the RBD image. In the case of
RWO volume. cephcsi makes sure only one
client is using the RBD image. If the rbd
image is mirrored, by default mirroring
daemon will add a watcher on the image
and as we are using go-ceph a watcher will
be added as we have opened the image So
we will have two watchers on an image if
mirroring is enabled. This holds when the
rbd mirror daemon is running, In case if
the mirror daemon is not running there will
be only one watcher on the rbd image
(which is placed by go-ceph image open)
we should not block the map operation if
the mirroring daemon is not running as
its Async mirroring. This commit adds a
check to make sure no more than 2 watchers
if the image is mirrored or no more than 1
watcher if it is not mirrored image.

8b8480017b logging: report issues in rbdImage.DEKStore API with stacks
It helps to get a stack trace when debugging issues. Certain things are
considered bugs in the code (like missing attributes in a struct), and
might cause a panic in certain occasions.

In this case, a missing string will not panic, but the behaviour will
also not be correct (DEKs getting encrypted, but unable to decrypt).
Clearly logging this as a BUG is probably better than calling panic().

b1d05a1840 rbd: repair encryption config in case it is missing
It is possible that when a provisioner restarts after a snapshot was
cloned, but before the newly restored image had its encryption metadata
set, the new image is not marked as encrypted. This will prevent
attaching/mounting the image, as the encryption key will not be fetched,
or is not available in the DEKStore.

By actively repairing the encryption configuration when needed, this
problem should be addressed.

0f8813d89f rbd:store/Read volumeID in/from PV annotation
In the case of the Async DR, the volumeID will
not be the same if the clusterID or the PoolID
is different, With Earlier implementation, it
is expected that the new volumeID mapping is
stored in the rados omap pool. In the case of the
ControllerExpand or the DeleteVolume Request,
the only volumeID will be sent it's not possible
to find the corresponding poolID in the new cluster.

With This Change, it works as below

The csi-rbdplugin-controller will watch for the PV
objects, when there are any PV objects created it
will check the omap already exists, If the omap doesn't
exist it will generate the new volumeID and it checks for
the volumeID mapping entry in the PV annotation, if the
mapping does not exist, it will add the new entry
to the PV annotation.

The cephcsi will check for the PV annotations if the
omap does not exist if the mapping exists in the PV
annotation, it will use the new volumeID for further
operations.

It seems that newer versions of some tools/libraries identify encrypted
filesystems with `crypto_LUKS` instead of `crypt`.

d7838defcf rbd: return FailedPrecondition error message
In case of the DR the image on the primary site cannot be
demoted as the cluster is down, during failover the image need
to be force promoted. RBD returns `Device or resource busy`
error message if the image cannot be promoted for above reason.
Return FailedPrecondition so that replication operator can send
request to force promote the image.

fb3f7fe202 rbd: remove todo for image not found
Incase of resync the image will get deleted, gets
recreated and its a a time consuming operation.
It makes sense to return aborted error instead
of not found as we have omap data only the image
is missing in rbd pool.

Do resync if the image is in unknow or in error
state.

Check for the current image state for up+stopped
or up+replaying and also all peer site status
should be un up+stopped to confirm that resyncing
is done and image can be promoted and used.
