Azure Disk is 256 GB but AKS is showing 8GB inside the Pod

Question

Hey there,

I think this is more like the K8S question together with AKS and Azure Disk.

I have an azure disk which is attached to the main VM of K8S.
In the screenshot, it is visible that the disk is 256 GB.

I have referenced the Volume like this in k8s,

But inside the POD, I can see the disk limit is only 8GB

Not sure, How to fix this issue. Couldn't find any possible way.

Help would be appreciated

Thanks

Hello @George Wolfi ,
Thanks for your query !
To repro your scenario I tried creating both static and dynamic volumes for Azure disks but I can see the size accordingly in the mounted container . Based upon the screen shot , I hope in your case the disk was created dynamically and you did use "PersistentVolumeClaim"

Followed the below article for static:

• https://learn.microsoft.com/en-us/azure/aks/azure-disk-volume Followed the below article for dynamic
• https://learn.microsoft.com/en-us/azure/aks/concepts-storage

Even tested it for StandardSSD.

All looks fine from my end

Couple of things to try:

• Can you try to delete the POD and re-create ?
• Sometimes this happens when you try to resize the PVC , can you try out the troubleshooting steps mentioned at https://github.com/kubernetes/kubernetes/issues/68427
• Try to recreate all the steps ?

If you are still facing the same issue , kindly provide all the detailed steps which you followed along with sample YAML , PVC , PV resources.
