500 Internal Server Error when pushing image to Openshift Internal Registry

[HowardM]

Hello,

I enabled the image registry for my single node Openshift cluster and configured it to use NFS storage, but when I try to push an image to it I get  500 Internal Server error as seen below:

sh-4.4# podman push image-registry.openshift-image-registry.svc:5000/openshift/nginx

Error: writing blob: initiating layer upload to /v2/openshift/nginx/blobs/uploads/ in image-registry.openshift-image-registry.svc:5000: received unexpected HTTP status: 500 Internal Server Error

Can anyone point me to the reason for this?

@HowardM Do you see anything in the registry logs : oc logs <registry_pod>  ?

Quite possible that the NFS share has messed up permissions.

check the ownership and permission of the file system if permission issue is found in above logs and set it accrodingly with the correct uid & gid.
