# volumeBindingMode: WaitForFirstConsumer

|
parameters:
|
|
# (required) String representing a Ceph cluster to provision storage from.
|
|
# Should be unique across all Ceph clusters in use for provisioning,
|
|
# cannot be greater than 36 bytes in length, and should remain immutable for
|
|
# the lifetime of the StorageClass in use.
|
|
# Ensure to create an entry in the configmap named ceph-csi-config, based on
|
|
# csi-config-map-sample.yaml, to accompany the string chosen to
|
|
# represent the Ceph cluster in clusterID below
|
|
clusterID: <cluster-id>
|
|
|
|
# (optional) If you want to use erasure coded pool with RBD, you need to
|
|
# create two pools. one erasure coded and one replicated.
|
|
# You need to specify the replicated pool here in the `pool` parameter, it is
|
|
# used for the metadata of the images.
|
|
# The erasure coded pool must be set as the `dataPool` parameter below.
|
|
# dataPool: <ec-data-pool>
|
|
|
|
# (required) Ceph pool into which the RBD image shall be created
|
|
# (optional) If the topologyConstrainedPools is provided
|
|
# eg: pool: rbdpool
|
|
pool: <rbd-pool-name>
|
|
|
|
# (optional) RBD image features, CSI creates image with image-format 2 CSI
|
|
# RBD currently supports `layering`, `journaling`, `exclusive-lock`,
|
|
# `object-map`, `fast-diff`, `deep-flatten` features.
|
|
# Refer https://docs.ceph.com/en/latest/rbd/rbd-config-ref/#image-features

|
|
|
# (optional) Options to pass to the `mkfs` command while creating the
|
|
# filesystem on the RBD device. Check the man-page for the `mkfs` command
|
|
# for the filesystem for more details. When `mkfsOptions` is set here, the
|
|
# defaults will not be used, consider including them in this parameter.
|
|
#
|
|
# The default options depend on the csi.storage.k8s.io/fstype setting:

# - ext4: "-m0 -Enodiscard,lazy_itable_init=1,lazy_journal_init=1"

|
# - xfs: "-K"
|
|
#
|

# mkfsOptions: "-m0 -Ediscard -i1024"
|
|
|
|
# (optional) Specifies whether to try other mounters in case if the current
|
|
# mounter fails to mount the rbd image for any reason. True means fallback
|
|
# to next mounter, default is set to false.
|
|
# Note: tryOtherMounters is currently useful to fallback from krbd to rbd-nbd
|
|
# in case if any of the specified imageFeatures is not supported by krbd
|
|
# driver on node scheduled for application pod launch, but in the future this
|
|
# should work with any mounter type.
|
|
# tryOtherMounters: false
|
|
|
|
# (optional) mapOptions is a comma-separated list of map options.
