- 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 Dorado 6.1.0 and later versions support NFS. Only OceanStor Dorado 6.1.3 and later versions support NFS 4.1. OceanStor Dorado 6.1.7 and later versions support NFS over RDMA. Only 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 Dorado 6.1.3 and later versions support multi-tenant.
