To recover from split brain (up+error) state the image need to be
demoted and requested for resync on site-a and then the image on site-b
should gets demoted.The volume should be marked to ready=true when the
image state on both the clusters are up+unknown because during the last
snapshot syncing the data gets copied first and then image state on the
site-a changes to up+unknown.
If the image state on both the sites are up+unknown consider that
complete data is synced as the last snapshot
gets exchanged between the clusters.
* create 10 GB of file and validate the data after resync
* Do Failover when the site-a goes down
* Force promote the image and write data in GiB
* Once the site-a comes back, Demote the image and issue resync
* Demote the image on site-b
* The status will get reflected on the other site when the last
snapshot sync happens
* The image will go to up+unknown state. and complete data will
be copied to site a
* Promote the image on site-a and use it

Adding labels to Pull-Requests can be done by Mergify. It is very useful
to filter PRs on their labels so that experts in certain areas can
identify PRs to review.
Adding labels is currently a complete manual process, this adds some
automation for it. There is no intention of it being complete, this is
mostly for getting started and trying things out.

The matching with regexes on the `base=` configuration in Mergify does
not seem to work as intended. Possibly this is due the addtional quotes
around the regex.

It is not always possible to automatically backport PRs to release
branches. That also means that these backport PRs are not created by the
mergify[bot] account. Because of this, it is needed to manually merge
PRs, as Mergify refuses to do it.
By changing the `base=` option to match a regular expression that
includes both `devel` and `release-*` branches, Mergify should assist
with merging PRs to release branches too.
Note that the `ci/centos` branch is different, as runs other tests than
the normal branches.

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
csi.CreateVolumeResponse based on an rbdVolume. Calling this helper
reduces the code duplication in CreateVolume().
Signed-off-by: Niels de Vos <ndevos@redhat.com>
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.
