Hello 

I setup the policies for backup job and it created snapshots successfully but failed at export operation with errors 

 

Looking at the volume pod error which is trying to create, it shows 
 

0/5 nodes are available: pod has unbound immediate PersistentVolumeClaims. preemption: 0/5 nodes are available: 5 Preemption is not helpful for scheduling.
AttachVolume.Attach failed for volume "kio-57c7a59970eb11ef8059e2b67c8c8805-0" : rpc error: code = Internal desc = failed to attach disk: "bbdf69b2-e841-493c-b015-b6d86a530292" with node: "423e15a9-8fjd-45d9-df64-64208ca72806" err failed to attach cns volume: "bbdf69b2-e841-493c-b015-b6d86a530292" to node vm: "VirtualMachine:vm-93261 3VirtualCenterHost: iu-op-vcsa01.abc.com, UUID: 423e14a9-8fed-45d9-df64-34208ca02806, Datacenter: Datacenter nDatacenter: Datacenter:datacenter-7, VirtualCenterHost: iu-op-vcsa01.abc.com]]". fault: "(*types.LocalizedMethodFault)(0xc001211f20)({\n DynamicData: (types.DynamicData) {\n },\n Fault: (types.CnsFault) {\n BaseMethodFault: (types.BaseMethodFault) <nil>,\n Reason: (string) (len=16) \"VSLM task failed\"\n },\n LocalizedMessage: (string) (len=32) \"CnsFault error: VSLM task failed\"\n})\n". opId: "89eb24e6"

but we have enough resources available to create more pods/pvcs.

Hi @msaeed 
  The error "failed to mount volume as 'ext4'; already contains xfs" generally occurs when the underlying virtual disk (VMDK) in vSphere has been formatted with a different file system than what the Kubernetes node expects.
  If you're using VMware's CSI driver, this mismatch might happen when: The VM’s disk is already formatted with a different file system, such as xfs, and Kubernetes is trying to mount it as ext4 by default. 
  So if you want to mount xfs volume to kubernetes pod, you might need to change the fstype parameter in storageclass. 
   Below, is the sample example storageclass with fstype parameter
   

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: vsphere-csi-sc
provisioner: csi.vsphere.vmware.com
parameters:
  fstype: xfs   # Make sure this matches the desired file system type
reclaimPolicy: Delete
volumeBindingMode: Immediate


Thanks,
Pavithra

Hi Pavithra 

Thanks for responding. 

I did the pre-flight vsphere_check with different storage class which is not xfs and tests were passed. 

But when I ran the job again for the same storage class in kasten, still the export jobs failed with same error as before

Also doing the csi_check returns

Hi @msaeed 
   Thanks for the clarification that you are using different storageclass now which is not xfs.
   
    So, Now this issue is related to vsphere csi and please find the below github issue for the same. 
    https://github.com/kubernetes-sigs/vsphere-csi-driver/issues/1416
   
   The solution for this would be to enable Changed Block Tracking (CBT) on existing worker nodes. 
   Please refer the vmware KB https://kb.vmware.com/s/article/88193
        
Thanks,
Pavithra

Hi Pavithra 

Thanks for you help and providing useful material. 
It has been resolved after enabling CBT

 

Thanks
