If any operations like Resize, Deleting
snapshot fails, we need to remove
both snapshot and the clone to avoid
resource leak.

The ReplicationServer is not used anymore, the functionality has moved
to CSI-Addons and the `internal/csi-addons/rbd` package. These last
references were not activated anywhere, so can be removed without any
impact.

When FilesystemNodeGetVolumeStats() succeeds, the volume must be
healthy. This can be included in the VolumeCondition CSI message by
default.
Checks that detect an abnormal VolumeCondition should prevent calling
FilesystemNodeGetVolumeStats() as it is possible that the function will
hang.

Issue:
The RoundOffCephFSVolSize() function omits the fractional
part when calculating the size for cephfs volumes, leading
to the created volume capacity to be lesser than the requested
volume capacity.
Fix:
Consider the fractional part during the size calculation so the
rounded off volume size will be greater than or equal to the
requested volume size.

Multiple go-routines may simultaneously create the

This commit safeguards subVolumeGroupCreated map

Multiple go-routines may simultaneously check for a clusterID's
presence in clusterAdditionalInfo and create an entry if it is
absent. This set of operation needs to be serialized.
Therefore, this commit safeguards clusterAdditionalInfo map
from concurrent writes with a mutex to prevent the above problem.

During ResyncVolume call, discard not found
error from GetMetadata API. If the image gets
resynced the local image creation time will be
lost, if the key is not present in the image
metadata then we can assume that the image is

Add support to create RWX clone from the
ROX clone, in ceph no subvolume clone is
created when ROX clone is created from a
snapshot just a internal ref counter is
added. This PR allows creating a RWX clone
from a ROX clone which allows users to create
RW copy of PVC where cephcsi will identify
the snapshot created for the ROX volume and
creates a subvolume from the CephFS snapshot.

During the Demote volume store

During Resync do below operation
* Check image creation timestamp
stored during Demote operation
and current creation timestamp during Resync
and check both are equal and its for
force resync then issue resync
* If the image on both sides is
not in unknown state, check
last_snapshot_timestamp on the
local mirror description, if its present
send volumeReady as false or else return
error message.
If both the images are in up+unknown the
send volumeReady as true.

Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes.
This Pool parameter is optional and only used as 'pool-layout' parameter
during subvolume and subvolume clone create request in cephcsi
and not used for Snapshot-backed volume at all.
It is not saved anywhere for use in subsequent operations after create too.
Therefore, We can set it to empty and not error out.

This commit makes sure sparsify() is not run when rbd

Running rbd sparsify with workload doing io and too
frequently is not desirable.

When a volume has AccessType=Block and is encrypted with LUKS, a resize
of the filesystem on the (decrypted) block-device is attempted. This
should not be done, as the application that requested the Block volume
is the only authoritive reader/writer of the data.
In particular VirtualMachines that use RBD volumes as a disk, usually
have a partition table on the disk, instead of only a single filesystem.
The `resizefs` command will not be able to resize the filesystem on the
block-device, as it is a partition table.
When `resizefs` fails during NodeStageVolume, the volume is unstaged and
an error is returned.
Resizing an encrypted block-device requires `cryptsetup resize` so that
the LUKS header on the RBD-image is updated with the correct size. But
there is no need to call `resizefs` in this case.
