Some testing on OpenShift has shown that enabling Hostnetworking causes
issues with ceph-volume creating OSD.
This is a pure Red Hat OpenShift downstream issue.
This is meant to be temporary while we are waiting for the Selinux team
to get back to us.

If a volume is being attached, it should be verified that the volume
is safe to attach. The volume was assumed to be safe to attach if it was
for the same pod. But this was assuming the pod of the same name would be
on the same node. This is true for pods created from deployments, but not
for pods that are part of a stateful set. A stateful set will maintain the
pod name even as the pod is failed over to a new node. Therefore, the fencing
much check if the pod is from the same node before allowing the attach to
continue. Otherwise, we need to wait for the volume to be detached from the
other node.

In Octopus, this commit
https://github.com/ceph/ceph/pull/30859/commits/c09b82a80a392ccd0da7677c7b424ce5cd3fa5d6
moved the quorum_status command to a socket call. Thus, the `ceph
quorum_status` command does not exist anymore, to use it we need to do
`ceph daemon mon.$ID quorum_status`. However, this command only works
locally so it won't work if we run it from the operator.
The `ceph mon_status` command is a general command that run from
anywhere and returns the mon map, let's use this one on the operator
code.
This is not a breaking change.

OSD on PVC does not upgrade when the user upgrades the ceph version on cluster-on-pvc yaml.
The solution incudes:
- upgrade osd prepare and daemon pods on upgrade
- skip c-v prepare if filesystem is already present on the pvc device.
- skip lvm release in case of upgrade.

PopulateDeviceInfo() in pkg/clusterd/disk.go returns nil as *sys.LocalDisk
if an error has occurred. This causes a nil pointer exception at
getAvailableDevices() in pkg/daemon/ceph/osd/daemon.go. At least the returned
value should be checked at the caller.
I added an explicit error to the return value of PopulateDeviceInfo(). This
naturally revokes an error check at the caller.
I modified PopulateDeviceUdevInfo() in the same file too.

We now differentiate the cases where:
* we only consume the external cluster
* we consume the external cluster as well as creating stateless
resources in Kubernetes (bootstrap mds,rgw, nfs)
This is mostly controlled via the image property spec. If not defined,
not extra CRs won't be able to be created.
Now the external cluster feature supports Ceph cluster as of Luminous 12.2.

A new CRD property `PreservePoolsOnDelete` has been added to Filesystem(fs) and
Object Store(os) resources in order to increase protection against data loss.
If it is set to `true`, associated pools won't be deleted when the main
resource(fs/os) is deleted. Creating again the deleted fs/os with the same name
will reuse the preserved pools.

Previously, we were applying lvm config changes to OSD running on PV. So
now, we do this for any type of cluster deployment (bare metal or
Cloud).

Previously, "run dir" was used to place a number of file and config on
dataDirHostPath. Now, since a lot of configs and options have moved
either on the OSD's startup CLI line or remove with bluestore we don't
need to change the default.
Also, it was confusing for user and difficult to find the socket.
The is is not breaking any config in dataDirHostPath since all the
elements (keyrings) are hardcoded in the config file.

RHEL8 introduces some lvm changes. For OSDs on PVs to work
we need to set allow_changes_with_duplicate_pvs = 1.

When running osds on pvc, the lvm is still holding the device when the cluster is deleted. As a result the PVs go into `failed` state
when the cluster is deleted. On deactivating the device, the 'failed' pvs get deleted as well. Solution involves:
- Running `lvchange -an <vg group name>` to deactivate the device.
- This command runs after 'osd prepare' completes.
- This command also runs after the 'osd daemon pod' is deleted or if the ceph-osd process terminates for some reasons.

Several commands were not using the cli finalizer function which builds
up the right argument to run a ceph command. This was working on the
operator since it used to have an /etc/ceph/ceph.conf file so we could
ran the command without specifying the ceph conf and key paths.
However, we recently removed that and it silently broke this "already"
broken code :).

OSD pods when running on PVC fail randomly due to some race condition:
- OSD daemon pod was activating the volume group using vgchange -an without any volume group name.
- This caused the pods to fail randomly when number of OSDs is more, say greater than 10.
- This fix adds Volume group name while activating/deactivating volume groups to fix this

Allow users to specify overrides in the CephCluster CRD. The override
ConfigMap still exists for emergency situations and is mounted into
daemon pods directly instead of being merged into a Rook-created config
file.
Rook Ceph no longer uses a config file for managing daemons with the
exception of the OSDs which still generate a config in an init
container.
