Troubleshoot Replication Issues
This section contains probable causes of and solutions to common replication problems.
Replication Conguration Error
Description Replication between the source and target NAS volumes fails because the source and target FluidFS
cluster topologies are incompatible.
Cause The source and target systems are incompatible for replication purposes.
Workaround Verify that both the source and target have the same number of NAS controllers.
Replication Target FluidFS Cluster is Busy
Description Replication between the source NAS volume and the target NAS volume fails because the target FluidFS
cluster is not available to serve the required replication.
Cause Replication fails because the target FluidFS cluster is not available to serve the required replication.
Workaround Verify the replication status on the target FluidFS cluster.
Replication Target File System is Busy
Description Replication between the source NAS volume and the target NAS volume fails because the target FluidFS
cluster le system is temporarily unavailable to serve the required replication.
Cause Replication fails because the target FluidFS cluster is temporarily unavailable to serve the required
replication.
Workaround The replication continues automatically when the le system releases part of the resources. Verify that
the replication continues automatically after a period of time (an hour).
Replication Target is Down
Description
Replication between the source NAS volume and the target NAS volume fails because the target NAS
volume is down.
Cause Replication fails because the le system of the target NAS volume is down.
Workaround Check whether the le system is down in the target system. If the FluidFS cluster le system is not
responding, you must start the le system on the target FluidFS cluster. The replication continues
automatically after the le system starts.
Replication Target is Not Optimal
Description
Replication between the source NAS volume and the target NAS volume fails because the target NAS
volume is not optimal.
Cause Replication fails because the le system of the target NAS volume is not optimal.
Workaround Check the system status of the target system to understand why the le system is not optimal. The
replication continues automatically after the le system recovers.
Replication Target Volume is Busy Reclaiming Space
Description
Replication between the source NAS volume and the target NAS volume fails because the target NAS
volume is busy freeing up space.
Cause Replication fails because the target NAS volume is busy freeing up space.
