First published on MSDN on Dec 08, 2014In the previous postwe have discussed how CSVFS abstracts failures from applications by going through the pause/resume state machine and we have also explained what the auto-pause is. Focus for this blog post will be auto-pauses.CSV auto pauses when it receives any failure from Direct IO or Block Redirected IO with a few exceptions like STATUSINVALIDUSERBUFFER, STATUSCANCELLED, STATUSDEVICEDATAERROR or STATUSVOLMGRPACKCONFIGOFFLINE, which indicate either user error or that storage is misconfigured. In both cases there is no value in trying to abstract the failure in CSV because as soon as the IO is retried it will get the same error.When File System Redirected IO fails (including any metadata IO) then CSV auto pauses only when error is one of the well knows status codes. Here is the list that we have as of Windows Server Technical Preview for vNext. Log Name: SystemSource: Microsoft-Windows-FailoverClusteringEvent ID: 5120Task Category: Cluster Shared VolumeLevel: ErrorDescription:Cluster Shared Volume 'Volume1' ('Cluster Disk 1') is no longer available on this node because of 'STATUSVOLUMEDISMOUNTED(C000026E)'. All I/O will temporarily be queued until a path to the volume is reestablished.Additional information is available in the CSV operational log channel Microsoft-Windows-FailoverClustering-CsvFs/Operational.
We encourage you to use the official Form RP-5217-PDF, Real Property Transfer Report available on our website, rather than unofficial forms available elsewhere. While the unofficial forms may appear to be similar, the resulting bar codes may not provide consistently accurate results. No information found about event id 5217.

This can be found in Event Viewer under ‘Applications and Services Logs Microsoft Windows FailoverClustering-CsvFs Operational’. Here is an Event 9296 logged to that channel. Get-PhysicalDisk Get-StorageReliabilityCounter ft DeviceId,ReadErrorsTotal,ReadLatencyMax,WriteErrorsTotal,WriteLatencyMax -AutoSizeThe list above is not exhaustive, but might give you some idea on how to approach the problem.SummaryIn this blog post we went over possible causes for the event 5120, what they might mean and how to approach troubleshooting. Windows Server has plenty of tools that would help you with troubleshooting 5120. Keep in mind that 5120 does not mean that your workload failed. Most likely cluster will successfully recover from that failure, and your workload will keep running. If recovery was not successful when you see event 5142, and that will be the subject of the next post.Thanks!Vladimir PetterPrincipal Software EngineerClustering & High-AvailabilityMicrosoftTo learn more, here are others in the Cluster Shared Volume (CSV) blog series:Cluster Shared Volume (CSV) Inside OutCluster Shared Volume DiagnosticsCluster Shared Volume Performance CountersCluster Shared Volume Failure Handling.

I built a new cluster recently and it was running solid an entire week without one Cluster Event in the logs. Over the weekend, one of the roles (VMs) decided to present itself with the failover threshold error, which I have seen numerous times in the past with HyperV Failover Clustering. For about half an hour, the VM moved into different states among different nodes and was probably offline during this timeframe.I google'd the event id's (1069,1205,1254) and found these TechNet articles:I don't see any treatments in the 'Resolve' sections that are not already in place.Any ideas? Anyone have experience with this same issue?Thanks!.
