RBD supports creating rbd images with object size, stripe unit and stripe count to support striping. This PR adds the support for the same. More details about striping at https://docs.ceph.com/en/quincy/man/8/rbd/#striping fixes: #3124 Signed-off-by: Madhu Rajanna <madhupr007@gmail.com>

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

|
|
# 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>

pool: <rbd-pool-name>

|
|
# (optional) RBD image features, CSI creates image with image-format 2 CSI

# RBD currently supports `layering`, `journaling`, `exclusive-lock`,

# (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
