Issue
When a node rebooted during an upgrade, the upgrade screen shows the node staying in a status of rebooting.
When verifing the logs on the StorageGRID Appliance, it shows:
/dev/mapper is empty

When the container is looking for the StorageGRID OS LUNs, its unable to find it so it sets up the node as a new installation.
