Hi,

I just try backup our on-prems self-hosted kubernetes cluster using kasten.

Kubernetes version : 1.23.5

CRI : containerd

Location Profile : NFS Filestore

Snapshot Drive : CSI

StorageClass, VolumeSnapshotClass and VolumeSnapshotContent

We got failed with message below :

Volume Snapshots are not supported for this storage provider

 

Output from validation tools :

Appreciate any suggestion.

Thanks

@Madi.Cristil @safiya - please move to the K10 board for better assistance.

Hi @diskominfo_jemberkab ,

As per the primer output it's trying to pull the version 4.5.13 which is not compatible with 1.23 k8s version. 

Try “helm repo update” before you execute the primer command . if it's Offline , pull the latest k10 charts to your local repository.

@Satish ,

I did helm repo update and re-install kasten chart. But pre-flight check result still same.

How to pull the latest k10 charts as you mention above ?

Hi @diskominfo_jemberkab 

What helm version you are using ? 

Can you provide the following :-

helm repo list |grep -i kasten

helm search repo k10

Regards
Satish

Hi @Satish ,

I’m sorry for late response.

kominfo@node1:~$ helm repo list |grep -i kasten
kasten  https://charts.kasten.io/
kominfo@node1:~$ helm search repo k10
NAME                    CHART VERSION   APP VERSION     DESCRIPTION
kasten/k10              6.5.1           6.5.1           Kasten’s K10 Data Management Platform
kasten/k10restore       6.5.1           6.5.1           A Helm chart for restoring K10 from a backup

 

 

Hello @diskominfo_jemberkab 

 

Would it be possible to try the following command.

 

curl -s https://docs.kasten.io/tools/k10_primer.sh  | bash /dev/stdin  -i gcr.io/kasten-images/k10tools:6.5.3

 

Thanks

Emmanuel
