The user should be able to fix the failed volumes and disks, then ask the {{DataNode}} to retry the previously failed volumes. > To attempt to reload the failed volume again on the same directory, this failed directory must not be presented in the {{Configuration}} object that {{DataNode has}}. Therefore, it should only put successfully loaded volumes into the {{Configuration}} object. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
