We have introduced a new goroutine to check the state of the rgw
endpoint. It will run every minute and perform operations on a bucket.
The success or failure will be reported as part of the status field of
the CephObjectStore CR.
A good status will look like:
status:
endpointStatus:
lastChanged: "2020-06-25T13:47:45Z"
lastChecked: "2020-06-25T13:48:46Z"
phase: Connected
A failed status:
status:
endpointStatus:
details: |-
error creating bucket "rook-ceph-internal-s3-bucket-checker": RequestError: send request failed

health: ERROR
This check works for both converged and external modes. Note that the
CephObjectStore CRD has a new field called "externalRgwEndpoints" which
allows you to define a list of IP addresses pointing to rgws.

We can now explicitly set any property on a given pool by using the new
Property field in the CephBlockPool Spec.
Also, this fixes the case where both `CephBlockPool` and `CephCluster`
are created at the same time. When Rook creates the pool, the cluster is
still being bootstrapped and the global option
`osd_pool_default_pg_autoscale_mode` has not bee set yet. So the pool
gets created but its `pg_autoscale_mode` property is set to `warn`
instead of `on`.

This is the final conversion to controller-runtime conversion. This time the
CephCluster CRD has been converted to use the controller-runtime
library.
The controller incorporates all the previous watchers too, so the Node
and hot-plug configmap are been watched too.
Only the operator setting configmap is not being watcher since it's not
related to the CephCluster CRD.
Not only the patch converts to controller-runtime but also tries to
re-organize the tree of the repo to actually make the code more
readable and have better functions/methods/tests separations.

As another option to run Ceph commands, a script can be executed
with Ceph commands as if running in the toolbox, but will instead
run in a job where the logs can be collected and analyzed
separately. This would be useful where automation is in place to collect
information about the cluster periodically or upon some failure
that is detected, without requiring an interactive shell.

Previously, the rbd-mirror daemon was integrated into the `CephCluster`
CRD. This wasn't really practical since we would have to wait for the
whole orchestration to be done to actually set it up. The same goes for
any CR update. Let's say you want to change the number of daemons, Rook
would go through mons, mgrs and osds until it get to rbd-mirror.
This triggers an undesired full orchestration.
With its own CRD this component just gains a lot more flexibility.

You can now use Rook along with Multus. Multus must be up and running
and the right ressources must exist such as NetworkAttachmentDefinition
CR.
The Cluster CR spec has new fields to work with multus:
network:
provider: multus (or 'host' for hostNetworking)
selectors:
public: NetworkAttachmentDefinition name
cluster: NetworkAttachmentDefinition name
If only a single NetworkAttachmentDefinition is provided Rook will use
both anyway for the Ceph traffic.
Please refer to the doc to learn more.

Now Kubernetes will perform liveness checks on mon, mds and osd daemons.
The command will:
* call the socket (check for existence)
* execute a command and check the return code (success if 0)
This handles the case where the daemon is stuck locally and
unresponsive. It's unlikely but not impossible.
These checks bring more robustness to the implementation.
rbd-mirror and nfs have been leftover for the following reason. The
rbd-mirror socket name is different from other daemons (could be fixed
though): /run/ceph/ceph-client.rbd-mirror.a.1.94362516231272.asok also,
the command to call would need to be changed from "status" to "rbd
mirror status" so we can keep this for a later.
The nfs ganesha has no socket only a PID file which doesn't mean much.
No PID means the process does not run so Kubernetes will already handle
this and the pod will crash loop.

When running on PVC, if the backend resizes the block, Rook will expand
it and the size of the OSD will grow.
Signed-off-by: Sébastien Han <seb@redhat.com>
We now support the addition of the PVC that acts as a metadata device
for a given OSD.
For this, you need to create a new `volumeClaimTemplates`, its name must
be "metadata" otherwise, Rook won't pick it up.
A template will look like this:
```
volumeClaimTemplates:
- metadata:
name: data
spec:
resources:
requests:
storage: 10Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
storageClassName: gp2
volumeMode: Block
accessModes:
- ReadWriteOnce
- metadata:
name: metadata
spec:
resources:
requests:
storage: 6Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
storageClassName: gp2
volumeMode: Block
accessModes:
- ReadWriteOnce
```
We now map block and block.db directly inside the container instead of
running ceph-volume activate. This is much cleaner.

Multiple things:
1. We removed all the function/methods/tests that were used to
create and manage rook legacy OSDS as well as bringing support to
Bluestore OSD only.
It also fixes various go-lint issues in the respectives files.
2. use c-v inventory to detect available devices:
Now we rely on the 'ceph-volume inventory' command to tell us if a
device is available or not.
3. implement raw mode for osd on pvc
When an OSD will be bootstrap on a PVC, the new c-v raw mode will be
used. It consists of putting block, db and wal under the same device.
Here LVM is out of the picture and the raw device is used as is. The
implementation is backward compatible so existing OSD on PVC will LVM
will continue to operate.

A new CRD option `continueUpgradeAfterChecksEvenIfNotHealthy` is added.
When upgrading, Rook goes OSD by OSD and then waits for PGs to be clean
before proceeding to the next OSD. Currently, Rook waits for 5 hours but
there might be circumstances where PGs need more time to settle.
Thus setting `continueUpgradeAfterChecksEvenIfNotHealthy` to true will
pursue the upgrade process, even if PGs are not 100% active+clean.

gp2 devices present themselves as SSDs,
but have much more variable performance.
Ceph attempts to adjust some settings based on the drive type,
HDD/SSD
In this case client I/O can be impacted too much by assuming gp2 devices are like other SSDs
(an example is https://bugzilla.redhat.com/show_bug.cgi?id=1765923#c6)
In order to prevent this, rook can set the following for OSDs
if the new CR setting `tuneSlowDeviceClass` is set to `true`:
```
osd_recovery_sleep = 0.1
osd_snap_trim_sleep = 2
osd_delete_sleep = 2

Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
Removing an OSD unintentionally can result in data loss,
which is to be prevented at all costs. Rook's functionality
to remove OSDs automatically when a node was removed from the
cluster CR has led on several occasions to users having OSDs
unintentionally removed from their cluster.
If the admin decides they really need to remove OSDs they should
do it as a one-time action that they intentionally run
rather than the operator attempting to manage the deletion
with desired state. The risk of misinterpreting the desired
state, even with a typo, is too great.
