Currently we have a bug that we are not using rados
namespace when adding ceph manager command to
remove the image from the trash. This commit
adds the missing rados namespace when adding
ceph manager task.
without fix the image will be moved to trash
and no task will be added to remove from the
trash. it will become ceph responsibility to
remove the image from trash when it will cleanup
the trash.
workaroud: manually purge the trash

RBD image metadata keys that start with '.rbd' are expected to be
internal to RBD itself and are not mirrored to remote sites. Renaming
the keys (dropping the '.' prefix) and using the new MigrateMetadata()
function now makes the keys available on remote sites too.
Closes: #2219

The new MigrateMetadata() function can be used to get the metadata of an
image with a deprecated and new key. Renaming metadata keys can be done
easily this way.
A default value will be set in the image metadata when it is missing
completely. But if the deprecated key was set, the data is stored under
the new key and the deprecated key is removed.

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.

It seems that the version of the key/value engine can not always be
detected for Hashicorp Vault. In certain cases, it is required to
configure the `VAULT_BACKEND` (or `vaultBackend`) option so that a
successful connection to the service can be made.
The `kv-v2` is the current default for development deployments of
Hashicorp Vault (what we use for automated testing). Production
deployments default to version 1 for now.

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.

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.

and applied to the vaultTenantConnection type by calling parseConfig().

This new KMS uses a Kubernetes ServiceAccount from a Tenant (Namespace)
to connect to Hashicorp Vault. The provisioner and node-plugin will
check for the configured ServiceAccount and use the token that is
located in one of the linked Secrets. Subsequently the Vault connection
is configured to use the Kubernetes token from the Tenant.

Mirror-snapshots can also be automatically created on a

The mirror-snapshot can be scheduled globally, per-pool,
or per-image levels. Multiple mirror-snapshot schedules

optional pool or image name; interval; and optional start time:
The interval can be specified in days, hours, or minutes
using d, h, m suffix respectively. The optional start-time
