Question
My organization has several Windows File Servers. How to access these Windows shared folders as storage volume on CP4D?
Answer
Cloud Pak for Data documentation has explanation about how to managing storage volumes, and also how to enabled users to connect to external SMB storage volumes. Following is sample steps to access Windows File Server as storage volume on CP4D cluster.
1. Confirm that the sharing folder set correctly in Windows server.
2. Install SMB CSI driver v1.11.0 version.
# curl -skSL https://raw.githubusercontent.com/kubernetes-csi/csi-driver-smb/v1.11.0/deploy/install-driver.sh | bash -s v1.11.0 --
Installing SMB CSI driver, version: v1.11.0 ...
3. Check pods status.
# kubectl -n kube-system get pod -o wide --watch -l app=csi-smb-controller
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
csi-smb-controller-c7ffbcd47-kmzmm 3/3 Running 100 (7h52m ago) 9d 192.168.26.145 master2.cp4d-hx.cp.mytest.org <none> <none>
# kubectl -n kube-system get pod -o wide --watch -l app=csi-smb-node

4. Create the required cluster role and cluster role binding for the meta-api.
# cat <<EOF | oc apply -f -

> kind: ClusterRole
> metadata:
> # "namespace" omitted. ClusterRoles are not scoped to a namespace.
> name: ibm-zen-volumes-cluster-role
> rules:

> # objects is "secrets"
> resources: ["persistentvolumes"]

> EOF
clusterrole.rbac.authorization.k8s.io/ibm-zen-volumes-cluster-role unchanged
clusterrolebinding.rbac.authorization.k8s.io/ibm-zen-volumes-cluster-role-binding unchanged
5. From CP4D UI, add storage volumes.
6. Confirm that the storage volume is running
7. On projects and deployment spaces, create connection to storage volumes.
8. Confirm that there is no problem to read and write to Samba storage volumes from python code.
9. Confirm the output file created in Windows server.
