glusterFS Management Daemon Error Scenarios

106001
Description: The operation could not be performed because the server quorum was not met.
Recommended Action: Ensure that the other peer Red Hat Storage nodes are online and reachable from the local peer Red Hat Storage node.
106002
Description: The local bricks belonging to the volume were killed because server-quorum was not met.
Recommended Action: Ensure that the other Red Hat Storage nodes are online and reachable from the local peer node.
106003
Description: Informational message: The local bricks belonging to the volume were restarted because server-quorum was met.
Recommended Action: None.
106004
Description: The glusterFS Management Daemon is either offline or the peer Red Hat Storage node is unreachable.
Recommended Action: Ensure that the glusterFS Management Daemon is running on the peer node or the firewall rules are not blocking the port 24007.
106005
Description: The brick process is offline.
Recommended Action:
  1. Identify the reason for the brick to go offline in the brick log files.
  2. Run the gluster volume start <VOLNAME> force command to bring the bricks back online.
106006
Description: Either the glusterNFS Server or Self-heal Daemon is offline.
Recommended Action:
  1. Investigate the Self-heal Daemon and glusterNFS Server log files for the reason for the brick to go offline.
  2. Run the gluster volume start <VOLNAME> force command to bring the glusterNFS Server and the Self-heal Daemon back online.
106007
Description:The rebalance process is offline.
Recommended Action: Execute the gluster volume rebalance <VOLNAME> status command and check if the rebalance status is complete, if not, then execute the command: gluster volume rebalance <VOLNAME> start
106008

Recommended Action: None.
106009
Description:A volume version mismatch occurred while adding a peer Red Hat Storage node.
Recommended Action: None.
106010
Description: A volume checksum version mismatch occurred while adding a peer Red Hat Storage node.
The log includes the peer name which caused the mismatch.
Recommended Action:
  1. Identify the node that is causing the checksum error.
  2. Contact the Red Hat Global Support.
106011
Description: A volume quota configuration version mismatch occurred while adding a peer Red Hat Storage node.
Recommended Action: None.
106012
Description: A quota configuration version checksum mismatch occurred while adding a Red Hat Storage node.
Recommended Action:
  1. Identify the node that is causing the checksum error. The log includes the peer name which caused the mismatch.
  2. Contact the Red Hat Global Support Services.
106013
Description: The brick process could not be brought offline.
Recommended Action:
  1. Identify the PID of the brick process from the log file.
  2. Kill the brick process manually.
106014
Description: One of the listed services: glusterNFS Server, Quota Daemon, Self Heal Daemon, or Brick Process could not be brought offline.
Recommended Action:
  1. Identify the PID of the process from the log file.

106018
Description: The rebalance process failed as the glusterFS Management Daemon could not establish an RPC connection.
Recommended Action:
  1. Identify the reason for failure in the log file to resolve the issue.
