- Note 1: Manage Provisioning is a volume management feature customized by Huawei CSI. This feature allows existing storage resources to be managed by Kubernetes. You are not allowed to manage a storage resource for multiple times and concurrently delete or create a storage resource.
- Note 2: If the user’s container platform is deployed in a virtualization environment, only iSCSI networking is supported.
- Note 3: If NVMe over RoCE or NVMe over FC is used, the version of the nvme-cli tool on worker nodes must be 1.9 or later. To query the version, run the nvme version command.
- Note 4: Only OceanStor/OceanStor Dorado 6.1.0 and later versions support NFS. Only OceanStor/OceanStor Dorado 6.1.3 and later versions support NFS 4.1. OceanStor/OceanStor Dorado 6.1.7 and later versions support NFS over RDMA. OceanStor/OceanStor Dorado 6.1.8 and later versions support NFS 4.2.
- Note 5: The provisioned PVC whose volumeType is lun and accessModes is ReadOnlyMany does not support capacity expansion.
- Note 6: Only system users can configure QoS.
- Note 7: Only the active-active (AA) mode is supported.
- Note 8: Only OceanStor/OceanStor Dorado 6.1.3 and later versions support multi-tenant.
