# after add storage to ocp cluster, wipe storage disk on this node
sgdisk --zap-all /dev/nvme0n1
# (echo n; echo p ; echo 1 ; echo ; echo +1200G; echo p ; echo w)  | sudo fdisk /dev/nvme0n1

# check ntp status
timedatectl
# if ntp not synchronized, update /etc/chrony.conf, the following entry works for me:
server gateway iburst
server clock01.util.phx2.redhat.com iburst
server clock02.util.phx2.redhat.com iburst
# then restart ntp service
systemctl restart chronyd

# Assign OCS label to storage node
oc label nodes baremetal cluster.ocs.openshift.io/openshift-storage=''
