Allocate space for disk on root device before creating PVC using local storage:

export ocpnode=88-a4-c2-47-69-5e

export ocpnode=$(oc get node | sed -n 2p | awk '{print $1}')

oc debug nodes/$ocpnode -- chroot /host ls -l /mnt
oc debug nodes/$ocpnode -- chroot /host mkdir -p /mnt/disk/registry
oc debug nodes/$ocpnode -- chroot /host chmod 777 /mnt/disk/registry
oc debug nodes/$ocpnode -- chroot /host chcon -Rt svirt_sandbox_file_t /mnt/disk/registry
oc debug nodes/$ocpnode -- chroot /host ls -lZ /mnt/disk

oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"pvc":{"claim":"image-registry-storage-local"}}}}'
oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"managementState":"Managed"}}'

oc patch config.imageregistry.operator.openshift.io/cluster --type=merge -p '{"spec":{"rolloutStrategy":"Recreate","replicas":1}}'
