Resizing Localpv hostpaths

[D1StrX]

Describe the problem/challenge you have While having a new storageClass with AllowVolumeExpansion: True, a storage size change of a PVC for a deployment isn't changing the size. Describing the PVC says it has the new spec, but Warning ExternalExpanding 14m volume_expand waiting for an external controller to expand this PVC

Describe the solution you'd like Allow volume expanding with dynamic-localpv-provisioner.

Environment:

• OpenEBS version (use kubectl get po -n openebs --show-labels): 4.1.1
• Kubernetes version (use kubectl version): 1.30
• Cloud provider or hardware configuration: Self-hosted
• OS (e.g: cat /etc/os-release): Ubuntu 22.04

Hi @D1StrX, there is no way to get the sigs k8s library that we use to support resize. You might want to follow this doc if you're using XFS/EXT4 quota: https://github.com/openebs/dynamic-localpv-provisioner/blob/develop/docs/tutorials/hostpath/xfs_quota/modify-xfs-quota.md

Ref: https://github.com/kubernetes-sigs/sig-storage-lib-external-provisioner/issues/43

If you're not using filesystem quota, the PV doesn't really limit your workloads to the PVC's 'capacity' value. The only limitation to your workloads would be the capacity of the filesystem. You'd not need to change the PVC size to be able to write beyond the storage capacity.

Good to know. Not using quotas 👌
