Hello! I try to backup a namespace containing a deployment with the following resources: deployments, service, configmap, secrets, pvc/pv (storageclass rook and nfs). It seems that I have problems with the nfs storageclass: If I try to backup every ressource I get an error “storageclass not supported”. Thats no problem I thought, because I tried: Excluding the pvc by name in the policy. But it got stuck in the phase “Snapshotting Application Components” Can you help me out with this, its freaking me out. Kubernetes 1.22 fresh installed K10 4.5.9

Okay it seems that I can snapshot again. Thanks a lot guys. I used the tools kubestr and the tools from the prerequisites to check anything.What I did:I downloaded again the files from the external-snapshotterhttps://github.com/kubernetes-csi/external-snapshotter(Just ignored anything except the “headings”Install Snapshot CRDsInstall Common Snapshot ControllerI deleted the deployed components with kubectl delete -f (snapshot crd AND snapshot-controller)I installed the snapshot CRDs i uninstalled in step 1 (but with kubectl apply -f crd/ not kubectl kustomize crd/ | kubectl apply -f - (that made problems)installed the snapshot controller uninstalled in step 1 (same here, just kubectl apply -f .I downloaded again the snapshotclass-yamls vor cephfs and rbdhttps://github.com/rook/rook/tree/master/deploy/examples/csiand applied them. Dont forget to add the annotations for k10 again!https://docs.kasten.io/latest/install/storage.html#csi-snapshot-configurationAfter that I retested my setup with kubestr and the prerequisites tool →DONE and OK!Tomorrow I will test the restore.Thanks a lot again to everyone. Have a nice evening

You made me unsure about the deployment of the volumesnapshotclass, but I have deployed it from this Documentation.Details:Rook-Ceph 1.7.4Ubuntu 20.04.3 LTS newest UpdatesKubernetes 1.22.2Containerd 1.4.12What about the deprecation message? Could this be a problem? How do you guys install the external-snapshotter? And which version? I can also post my volumesnapshotclasses if needed.

Policy fails or got stuck in "Snapshotting Application Components"

Hi, thanks for posting in the forums. Can you post some more details about your storageclass? Is it a CSI based storage class? Can you post the output of “kubectl get sc” command?

If it’s a CSI based storageclass can you test the CSI with the opensource tool “kubestr” https://kubestr.io/

Run ./kubestr csicheck -s <storage class> -v <volume snapshot class>
and post the results?

Rather than excluding the storageclass PVCs, why not configure it so it can snapshot?
Before you deployed Kasten, did you run the pre-flight/primer script to validate that your storageclass and snapshotclass is setup?
curl https://docs.kasten.io/tools/k10_primer.sh | bash

You can harmlessly run it after you’ve already deployed which will temporarily create a small pod and PVC on each storageclass, snapshot it, and then delete it. You should get all ‘OK’.

At first, thanks a lot for the response.

Hi, thanks for posting in the forums. Can you post some more details about your storageclass? Is it a CSI based storage class? Can you post the output of “kubectl get sc” command?

If it’s a CSI based storageclass can you test the CSI with the opensource tool “kubestr” https://kubestr.io/

Run ./kubestr csicheck -s <storage class> -v <volume snapshot class>
and post the results?

I did the steps you told me, here are the results:

# kubectl get sc

And I tried to do a snapshot with kubestr (wow I didnt know that!) - but that result is very confusing, because I was able to snapshot before in this cluster:

# ./kubestr csicheck -s rook-ceph-block -v csi-rbdplugin-snapclass

Rather than excluding the storageclass PVCs, why not configure it so it can snapshot?
Before you deployed Kasten, did you run the pre-flight/primer script to validate that your storageclass and snapshotclass is setup?
curl https://docs.kasten.io/tools/k10_primer.sh | bash

You can harmlessly run it after you’ve already deployed which will temporarily create a small pod and PVC on each storageclass, snapshot it, and then delete it. You should get all ‘OK’.

I did this before installing k10 - the results seemed okay to me (I googled “Missing/Failed to Fetch CSIDriver Object” - but that shouldn’t be a problem according to kasten-io.

additionially, I have to say, that I dont use a Snapshotclass for the nfs mount. Let me show the yaml to this:

---
  apiVersion: v1
  kind: PersistentVolume
  metadata:
    name: pv-k10-backup
  spec:
    storageClassName: ""
    capacity:
      storage: 1024Gi
    accessModes:
      - ReadWriteOnce
    claimRef:
      namespace: kasten-io
      name: pvc-k10-backup
    nfs:
      server: <IP-TO-NFS-SERVER>
      path: "/vol/backup/k10/"

---
  apiVersion: v1
  kind: PersistentVolumeClaim
  metadata:
    name: pvc-k10-backup
    namespace: kasten-io
  spec:
    accessModes:
      - ReadWriteOnce
    storageClassName: ""
    resources:
      requests:
        storage: 1024Gi

Thanks a lot!

Kubestr tests the same behavior as Kasten K10 - meaning that if Kubestr fails, Kasten will as well. Rook/Ceph should support volumesnapshot capability as documented here: https://github.com/rook/rook/blob/master/Documentation/ceph-csi-snapshot.md

Can you confirm your volumesnapshot class is set up as in this documentation? Also can you provide the Kubernetes version and distro you are running?

It’s also possible to set up Kasten K10 to use “generic” backup - bypassing the CSI snapshot functionality - see https://docs.kasten.io/latest/install/generic.html

You made me unsure about the deployment of the volumesnapshotclass, but I have deployed it from this Documentation.

Details:

Rook-Ceph 1.7.4
Ubuntu 20.04.3 LTS newest Updates
Kubernetes 1.22.2
Containerd 1.4.12

What about the deprecation message? Could this be a problem? How do you guys install the external-snapshotter? And which version? I can also post my volumesnapshotclasses if needed.

I got stuck on this with Rook/Ceph as well. If I remember correctly I used the these instructions in git hub:

Although it has a snapshotclass which mine would not allow me to apply the manifest in rook because the I was missing the snapshoter. I did once for some reason lack a snapshotcontroller once, so might be a good idea to go over the github stuff just in case.

Okay it seems that I can snapshot again. Thanks a lot guys. I used the tools kubestr and the tools from the prerequisites to check anything.

What I did:

I downloaded again the files from the external-snapshotter https://github.com/kubernetes-csi/external-snapshotter (Just ignored anything except the “headings”
- Install Snapshot CRDs
- Install Common Snapshot Controller
I deleted the deployed components with kubectl delete -f (snapshot crd AND snapshot-controller)
I installed the snapshot CRDs i uninstalled in step 1 (but with kubectl apply -f crd/ not kubectl kustomize crd/ | kubectl apply -f - (that made problems)
installed the snapshot controller uninstalled in step 1 (same here, just kubectl apply -f .
I downloaded again the snapshotclass-yamls vor cephfs and rbd https://github.com/rook/rook/tree/master/deploy/examples/csi and applied them. Dont forget to add the annotations for k10 again! https://docs.kasten.io/latest/install/storage.html#csi-snapshot-configuration

After that I retested my setup with kubestr and the prerequisites tool → DONE and OK!

Tomorrow I will test the restore.

Thanks a lot again to everyone. Have a nice evening

Hi , I’m facing the similar issue-

curl -s https://docs.kasten.io/tools/k10_primer.sh | bash - Looks all ok.

Validate Generic Volume Snapshot:
Pod created successfully - OK
GVS Backup command executed successfully - OK
Pod deleted successfully - OK

Here is the output of - kubectl get sc command

root@k8s-masterk10:~# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
standard (default) k8s.io/minikube-hostpath Delete Immediate false 11d
root@k8s-masterk10:~#

Please suggest.
