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.

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().

The default number for cloning and snapshot/restore is 10 volumes. This
adds to the time the test suite runs. There is no need to validate 10
copies of the encrypted volume, a single copy is sufficient.

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.

buildCreateVolumeResponse() exists exactly for the need to create a

The rbdVolume that needs its encryption configured is constructed in the
Exists() method. It is suitable to move the copyEncryptionConfig() call
there as well, so that the object is completely constructed in a single
place.
Golang-ci:gocyclo complained about the increased complexity of the
Exists() function. Moving the repairing of the ImageID into its own
helper function makes the code a little easier to understand.

The new StoreCryptoPassphrase() method makes it possible to store an

Cloning volumes will use this, as the passphrase from the original

The ControllerServer should not need to care about support for

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.
