This commit adds `GetCephFSRadosNamespace` util method that returns the `RadosNamespace` specified in ceph-csi-config ConfigMap under cephFS.radosNamespace. If not specified, the method returns the default RadosNamespace i.e, csi. Signed-off-by: Praveen M <m.praveen@ibm.com>

# This is a sample configmap that helps define a Ceph cluster configuration
|
|
# as required by the CSI plugins.
|
|
apiVersion: v1
|
|
kind: ConfigMap
|
|
# Lets see the different configuration under config.json key.
|
|
# The <cluster-id> is used by the CSI plugin to uniquely identify and use a
|
|
# Ceph cluster, the value MUST match the value provided as `clusterID` in the
|
|
# StorageClass
|
|
# The <MONValue#> fields are the various monitor addresses for the Ceph cluster
|
|
# identified by the <cluster-id>
|
|
# If a CSI plugin is using more than one Ceph cluster, repeat the section for
|
|
# each such cluster in use.
|
|
# To add more clusters or edit MON addresses in an existing configmap, use
|
|
# the `kubectl replace` command.
|
|
# The "rbd.rados-namespace" is optional and represents a radosNamespace in the
|
|
# pool. If any given, all of the rbd images, snapshots, and other metadata will
|
|
# be stored within the radosNamespace.
|
|
# NOTE: The given radosNamespace must already exists in the pool.
|
|
# NOTE: Make sure you don't add radosNamespace option to a currently in use
|
|
# configuration as it will cause issues.
|
|
# The "rbd.mirrorDaemonCount" is optional and represents the total number of
|
|
# RBD mirror daemons running on the ceph cluster.
|
|
# The field "cephFS.subvolumeGroup" is optional and defaults to "csi".
|
|
# NOTE: The given subvolumeGroup must already exist in the filesystem.
|
|
# The "cephFS.netNamespaceFilePath" fields are the various network namespace
|
|
# path for the Ceph cluster identified by the <cluster-id>, This will be used
|
|
# by the CephFS CSI plugin to execute the mount -t in the
|
|
# The "cephFS.kernelMountOptions" fields are comma separated mount options
|
|
# for `Ceph Kernel client`. Setting this will override the kernelmountoptions
|
|
# command line flag.
|
|
# The "cephFS.fuseMountOptions" fields are common separated mount options
|
|
# for `Ceph FUSE driver`. Setting this will override the fusemountoptions
|
|
# command line flag.
|
|
# The "cephFS.radosNamespace" is optional and represents a radosNamespace in the
|
|
# metadata pool. If any given, the omap data of cephFS will be stored within
|
|
# this radosNamespace.
|
|
# NOTE: Make sure you don't add radosNamespace option to a currently in use
|
|
# configuration as it will cause issues.
|
|
# network namespace specified by the "cephFS.netNamespaceFilePath".
|
|
# The "nfs.netNamespaceFilePath" fields are the various network namespace
|
|
# path for the Ceph cluster identified by the <cluster-id>, This will be used
|
|
# by the NFS CSI plugin to execute the mount -t in the
|
|
# network namespace specified by the "nfs.netNamespaceFilePath".
|
|
# The "rbd.netNamespaceFilePath" fields are the various network namespace
|
|
# path for the Ceph cluster identified by the <cluster-id>, This will be used
|
|
# by the RBD CSI plugin to execute the rbd map/unmap in the
|
|
# network namespace specified by the "rbd.netNamespaceFilePath".
|
|
# The "readAffinity" fields are used to enable read affinity and pass the crush
|
|
# location map for the Ceph cluster identified by the cluster <cluster-id>,
|
|
# enabling this will add
|
|
# "read_from_replica=localize,crush_location=<label:value>" to the map option.
|
|
# If a CSI plugin is using more than one Ceph cluster, repeat the section for
|
|
# each such cluster in use.
|
|
# NOTE: Changes to the configmap is automatically updated in the running pods,
|
|
# thus restarting existing pods using the configmap is NOT required on edits
|
|
# to the configmap.
|
|
|
|
# Lets see the different configuration under cluster-mapping.json key.
|
|
# This configuration is needed when volumes are mirrored using the Ceph-CSI.
|
|
# clusterIDMapping holds the mapping between two clusterId's of storage
|
|
# clusters.
|
|
# RBDPoolIDMapping holds the mapping between two poolId's of storage clusters.
|
|
# CephFSFscIDMapping holds the mapping between two FscId's of storage
|
|
# clusters.
