Trident can not delete, create or map nvme/tcp namespaces to subsystems while in failover on a metrocluster ip #869

Closed sithglan closed 1 year ago

sithglan commented 1 year ago

Describe the bug Trident v23.10.0 can not delete, create, map nvme/tcp namespaces to subsystems while in failover on a metrocluster ip.

Environment Upstream Kubernetes v1.28.3, trident v23.10.0, metrocluster ip aff a220 9.13.1P2

curl -sL https://github.com/NetApp/trident/releases/download/v23.10.0/trident-installer-23.10.0.tar.gz | tar -xzf - cd trident-installer sudo cp tridentctl /usr/local/bin kubectl apply -f deploy/namespace.yaml echo ' enableACP: true' >> ~/trident-installer/deploy/crds/tridentorchestrator_cr.yaml echo ' acpImage: registry-06.d.tg.st/trident-acp:23.10.0' >> ~/trident-installer/deploy/crds/tridentorchestrator_cr.yaml echo ' imagePullSecrets:' >> ~/trident-installer/deploy/crds/tridentorchestrator_cr.yaml echo ' - astra-registry-cred' >> ~/trident-installer/deploy/crds/tridentorchestrator_cr.yaml kubectl create -f deploy/bundle_post_1_25.yaml kubectl create -f deploy/crds/tridentorchestrator_cr.yaml

To Reproduce https://tg.st/u/ea96f55c3d0cea869670eef24a479972afe70755d90893d548d658f7918a7eb0.txt

Expected behavior When metrocluster ip is in switchover, I expect to be able to create and remove nvme/tcp pv(c)s.

Additional context default 25s Warning FailedAttachVolume pod/nvme-pod AttachVolume.Attach failed for volume "pvc-31688855-f55c-441d-b8b0-12abe5c15519" : volume attachment is being deleted default 1s Warning VolumeFailedDelete persistentvolume/pvc-31688855-f55c-441d-b8b0-12abe5c15519 persistentvolume pvc-31688855-f55c-441d-b8b0-12abe5c15519 is still attached to node debian-01-02

To my best knowledge, NVMe/TCP ist currently not supported on Metrocluster, and the docs seem to agree: "MetroCluster configurations are not supported on NVMe/TCP."

https://docs.netapp.com/us-en/ontap/nvme/support-limitations.html#features

In essence, I think this is not a Trident issue, as the underlying storage configuration itself is currently unsupported.

Sorry for being the bearer of bad news :-(

You're right. Thank you for the heads up. I was under the impression that I read that nvme/tcp is supported for metrocluster ip and I'm using it since 30th March. Anyway neither the documentation nor IMT says it is supported. So I must have been mistaken. Closing the issue.
