Administrator Guide
Tx_pause for eth(x) on node 1 is off.
Cause Flow control is not enabled on the switch(es) connected to a FluidFS cluster controller.
Workaround See the switch vendor's documentation to enable ow control on the switch(es).
Troubleshoot Replication Issues
This section contains probable causes of and solutions to common replication problems.
Replication Conguration 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.
