Thank you for the prompt reply.

 

I have this set in master-config.yaml under kuberneteMasterConfig:

 

feature-gates:

  - ExpandPersistentVolumes: True

 

 

I have this set in node-config.yaml under kubeletArguments:

 

  feature-gates:

  - ExpandPersistentVolumes=true

 

Thanks,

I think you not have feature gate enabled properly. I would double check and ensure that it is correctly enabled.

I’ve installed gluster using the playbook playbooks/openshift-glusterfs/config.yml from release-3.9 checkout.  Install and config and storage project all come up and are running ok.  When I try to add ‘allowVolumeExpansion’ to my storage class (either by oc replace, patch,  or –f newstorageclass.yml) the storage class is created or modified. However, the option does not stay.  So I’m unable to resize pv by editing a new pvc created on that sc.

I’ve set the feature gate, `ExpandPersistentVolumes` in both master-config.yaml and node-config.yaml. In previous test installs I don’t recall setting an admission controller for called `PersistentVolumeClaimResize?

Am I missing something? If I need to set the admission controller, what’s the best way to enable that? I’ve manually added to the admin config plugin, with no success.

Can anyone help with proper config to get pv resize working again?

My inventory for Gluster
# Glusterfs # CNS storage for applications
openshift_storage_glusterfs_namespace: app-storage
openshift_storage_glusterfs_nodeselector: 'region=storage'
openshift_storage_glusterfs_block_deploy: False
openshift_storage_glusterfs_is_native: True
openshift_storage_glusterfs_storageclass_default: True
openshift_storage_glusterfs_timeout: 600
openshift_storage_glusterfs_wipe: True

openshift_storage_glusterfs_is_missing: False
openshift_storage_glusterfs_heketi_is_missing: True


Thanks,

Todd
