Currently we are assuming that only one rbd mirror daemon running on the ceph cluster but that is not true for many cases and it can be more that one, this PR make this as a configurable parameter. fixes: #4312 Signed-off-by: Madhu Rajanna <madhupr007@gmail.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.
|
|
# 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.
