Disk replication falling behind

38750103 - DRBD Sentinel: Disk replication is falling behind. See log for details.

Explanation

If the replication queue fills on the primary appliance, system load on the primary might increases. Replication issues are commonly caused by performance issues on the primary system, or storage issues on the secondary system, or bandwidth problems between the appliances.

User response

Select one of the following options:

  • Review bandwidth activity by loading a saved search MGMT: Bandwidth Manager from the Log Activity tab. This search displays bandwidth usage between the console and hosts.
  • If SAR sentinel notifications are recurring on the primary appliance, Distributed Replicated Block Device queues might be full on the primary system.
  • Use SSH and the cat /proc/drbd command to monitor the Distributed Replicated Block Device status of the primary or secondary hosts.
