CES configuration issues

The following are the issues that you might encounter while configuring cluster export services in IBM Storage Scale.

  • Issue: The mmces command shows a socket-connection-error.

    Error: Cannot connect to server(localhost), port(/var/mmfs/mmsysmon/mmsysmonitor.socket): Connection refused

    Solution: The mmsysmon-daemon is not running or is malfunctioning. Submit the mmsysmoncontrol restart command to restore the functionality.

  • Issue: The mmlscluster --ces command does not show any CES IPs, bound to the CES-nodes.
    Solution: Either all CES nodes are unhealthy or no IPs are defined as CES IPs. Try out the following steps to resolve this issue:
    1. Use the mmces state show -a to find out the nodes in which the CES service is in the FAILED state. Using the ssh <nodeName> mmhealth node show command displays the component that is creating the issue. In some cases, events are created if there are issues with the node health.
    2. Use the mmces address list command to list the IPs are defined as CES IPs. You can extend this list by issuing the command mmces address add --ces-node --ces-ip <ipAddress>.
