6027-4204 [E] Not enough CCR quorum nodes available.

Explanation

A CCR request failed due to a loss of a majority of quorum nodes. To fulfill a CCR request the IBM Storage Scale daemons (mmsdrserv or mmfsd) must communicate with each other on a majority of quorum nodes. Most of the IBM Storage Scale commands will not work because the IBM Storage Scale commands use the CCR. Possible reasons for the failure are:
  1. A majority of quorum nodes are down.
  2. The IBM Storage Scale daemon (mmsdrserv or mmfsd) is not running on a majority of quorum nodes.
  3. A communication problem might exist among a majority of quorum nodes.

User response

  1. Make sure that a majority of quorum nodes are up.
  2. Verify that either the mmsdrserv daemon (if IBM Storage Scale is down) or the mmfsd daemon (if IBM Storage Scale is active) is running on a majority of quorum nodes (for example, on Linux® by issuing the ps command).
  3. Make sure the IBM Storage Scale daemons can communicate with each other on a majority of quorum nodes. To identify the problem, issue the mmhealth node show GPFS -v command or the mmnetverify command as described in the topic Analyze network problems with the mmnetverify command.
