Setting bytes-to-inode ratio on AKS storage class

  • 772

I'm hitting inode limits on an AKS cluster in a volume (ext4) provisioned with Azure Disk Provisioner.

I've found the docs on the CSI Driver, but there's no mention on how to choose the target filesystem or formatting options.

How can I choose the filesystem used or the options given to the mkfs command (like setting the bytes to inode ratio on ext4) on creation?

    While it seems to be impossible to directly influence file system formatting options, changing the filesystem to another is possible:

    apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: ssd-xfs
parameters:
  fsType: xfs # <------
  skuName: StandardSSD_LRS
provisioner: disk.csi.azure.com

    This alleviates the inode exhaustion issue somewhat.
