|
.Prerequisite for cluster creation
|
|
|
|
* You have the option to select the root disk sizing for the default machine pool during cluster installation.
|
|
|
|
.Procedure for cluster creation
|
|
|
|
* Run the following command when creating your OpenShift cluster for the desired root disk size:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa create cluster --worker-disk-size=<disk_size>
|
|
----
|
|
The value can be in GB, GiB, TB, or TiB. Replace '<disk_size>' with a numeric value and unit, for example '--worker-disk-size=200GiB'. You cannot separate the digit and the unit. No spaces are allowed.

|
* You have the option to select the root disk sizing for the new machine pool after the cluster has been installed.

[source,terminal]
|
|
----
|
|
$ rosa create machinepool --cluster=<cluster_id> <1>
|
|
--disk-size=<disk_size> <2>
|
|
----
|
|
<1> Specifies the ID or name of your existing OpenShift cluster
|
|
<2> Specifies the worker node disk size. The value can be in GB, GiB, TB, or TiB. Replace '<disk_size>' with a numeric value and unit, for example '--disk-size=200GiB'. You cannot separate the digit and the unit. No spaces are allowed.
