Describe the bug

I used the /datastoreresources endpoint to find the fcdId of the volume I want to migrate.

{
    "datacenter": "MyDatacenter",
    "datastore": "SourceDatastore",
    "totalVolumes": 132,
    "containerVolumes": [
        {
            "fcdId": "287e1630-26f6-419e-a375-b2bdba724710",
            "fcdName": "pvc-9d6aa201-2bae-4b96-91f7-9a48d574b98d",
            "attachmentDetails": {
                "attached": true,
                "vm": "staging-master-pool-7ccf8d9669-97m66"
            },
            "host": "10.165.32.191"
        },

When sending the following request I get the error below:

curl --location --request POST 'http://10.166.153.15:30008/1.0.0/migratevolumes?datacenter=MyDatacenter&targetDatastore=TargetDatastore&fcdIdsToMigrate=287e1630-26f6-419e-a375-b2bdba724710' \
--header 'Accept: application/json' \
--header 'Authorization: Basic XYZ' \
--data-raw ''

{
    "message": "failed to migrate volumes.",
    "error": "the server could not find the requested resource"
}

Reproduction steps

  1. Post to /migratevolumes? with fcdId from /datastoreresources

Expected behavior

Should return job-id

Can you paste the cns-manager container logs for volume migration?

2023-07-06T08:35:39.805Z ERROR MigrateVolumes datastore/utils.go:393 unable to list CSINodeTopologis for cluster {"TraceId": "92df8cff-8b4c-4c76-a440-2c930787c292", "clusterID": "demo", "error": "the server could not find the requested resource"}

Can you list and see if you have any csinodetopology object in your source volume k8s cluster? The output should be something like this:

> kubectl get csinodetopologies

NAME                         AGE
k8s-control-418-1685678575   34d
k8s-control-572-1685678615   34d
k8s-control-830-1685678594   34d
k8s-node-174-1685678656      34d
k8s-node-366-1685678635      34d
k8s-node-873-1685678675      34d

In your setup, CNS manager is unable to find the CSINodeTopology CR that vSphere CSI driver creates during node discovery which contains the topology labels for a CSI node. CNS manager relies on it to get the topology information for k8s cluster nodes.
What's the kubernetes distribution you're using, is it a packaged distribution like Openshift or Anthos? It would be good to know that along with the CSI driver version.

Hey same issue here.

The cluster was deployed with Rancher. The "add-on" section during the cluster deployment in rancher with vsphere node driver was used to deployed CSI storage plugin.

When I try to get csinodetopologies their is no resources :/

kubectl get csinodetopologies
error: the server doesn't have a resource type "csinodetopologies"

It's possible to create it post CSI deployment ?

rancher version : v2.6.8

Hey,

I updated the kube cluster and also updated CSI config (through rancher add-on)

Options used for the CSI:
image

Now I can submit new volume migration jobs but I have an issue with the x509 for the cluster registered to the cns-manager.
During the registration I try to use kubeconfig file with: insecure-skip-tls-verify: true option but same error.

apiVersion: v1
kind: Config
clusters:
- cluster:
    insecure-skip-tls-verify: true
    server: https://xxx
  name: cnsmgr-cluster
...
kubectl get volumemigrationjobs.cnsmanager.cns.vmware.com -n cns-manager
NAME                                                      AGE
volumemigrationjob-07d2b76e-4d95-11ee-8a33-764b5b0165e1   36m

The error returned by the cns-manager:

Hey,

Just for tracking, if that can help someone.

I had this x509 issue because rancher act as auth proxy for my workload cluster.
In my case rancher was deployed with cert-manager issuing ssl cert from letsencrypt.
In this case, rancher don't manage ssl certs and so don't generate the certificate-authority-data field in the kubeconfig files for workload cluster.

If this field is not provided or if insecure-skip-tls-verify: true in kubeconfig is set, cns-manager return error x509: certificate signed by unknown authority"

After providing base64 encoded full-chain of the rancher server certificate in kubeconfig (in certificate-authority-data field) the volume migration job succeed.

Thanks for the help,
kiki

@ccleouf66 We have not tested this with Rancher. Glad you were able to overcome different issues to make it run on Rancher.
IIUC from the screenshot you attached, enabling CSI topology plugin would have created csinodetopologies objects.

@gohilankit yes, to be honest, I don't remember witch one was not enabled before, but with this features enabled on rancher deploying the CSI plugin, csinodetopologieswas created.
