  • Hello,

    To take a further investigation for this issue, you can find additional information in Event Viewer under  ‘Applications and Services Logs \ Microsoft \ Windows \ FailoverClustering-CsvFs \ Operational’.

    It contains the source of the auto-pause, and in some cases may contain additional parameters helping to further narrow down the scenario. 

    More details about Troubleshooting Cluster Shared Volume Auto-Pauses, you can see the following article.

  • Lots of people are having the same issue after the rolling upgrade from WS 2012R2 to WS 2016. Is this your case?

  • Same here.

    EDIT : Server 2016 Hyper-V Cluster.

    Not really sure if this is related to when we are performing Veeam Backup.

    Any suggestions Microsoft?

    Do you think this is related to the upgrade rather than just because VSS is using the CSV for Checkpoints?

    Has anybody confirmed that KB4025334 solves this?

  • We are also seeing this warning, though less frequently. We upgraded our cluster from 2012 R2 -> 2016 and are backing up our VMs with VEEAM.

  • I had an outage yesterday and believe its related to this.

    My 2016 hosts lost access to the shared storage with the error:

    The IO operation at logical block address 0xdad30b0 for Disk 3 (PDO name: \Device\MPIODisk3) was retried.

    I have also seen these errors in event viewer.

    Cluster Shared Volume 'Volume6' ('Cluster Disk 5') has entered a paused state because of 'STATUS_USER_SESSION_DELETED(c0000203)'. All I/O will temporarily be queued until a path to the volume is re-established.

    I have applied KB4025334.

    I also use Veeam Backup & Recovery 9.5 update 3 to backup the cluster roles.

    Is there an update on this?

    Best regards,

    Ben

  • Having the same issues here since upgrading to server 2016.  Have all of the updates current.  I get csv pauses every hour exactly, someimes every 30 minutes.  Tried disabling Veeam backups, still get the errors.  Have also had VM pauses and crashes related to this issue.

    Server 2012r2 worked just fine.  SAS HBAs firmware and drivers updated.  So far nothing has made it any better.

    Thanks!

  • having this issue too. between 30 minutes and 2 hours. OpsMgr reports this warning every time. Using DELL R740 with FC HBA firmware and drivers up to date.

  • Same problem here ... dell 730dx, windows server 2016, veeam b&r 9.5-3

  • we've been troubleshooting this for over a year. Updates all installed, latest firmware and bios on all equipment, checked nics and settings for hyper-v. Still get these weekly.

    really I think 2016 is simply broken.  There's rds issues as well since RTM which haven't been addressed.

    basically, we gave up and now waiting for server 2019

  • Lucas, not seeing anything about STATUS_USER_SESSION_DELETED in that KB...

  • How many cluster shared volumes do you have in the cluster, and how many Hyper-V hosts? I've seen this error escalating when the number of CSV are greater than the number of hosts in the cluster.

    It seems that if a Hyper-V server hosts more than one CSV at a time, this error sometimes occur.

    Tuesday, August 28, 2018 7:41 AM
  • KB4338822 doesn't work for me. I confirmed that it is installed on all cluster nodes, but as soon as too many VMs are running on CSVs that are not owned by the cluster node the VM is running on, the error occurs.

  • Hi Carsten,

    Right, please check the versions of Integration Services of VMs they need to be same.

    If no update it :)

    Check too, the configuration of heartbeat, check this one 

    https://blogs.msdn.microsoft.com/clustering/2012/11/21/tuning-failover-cluster-network-thresholds/

    In my cluster I've set as below.

    PS C:\Windows\system32> (get-cluster).SameSubnetDelay = 2000
    PS C:\Windows\system32> (get-cluster).SameSubnetThreshold= 20 
    PS C:\Windows\system32> (get-cluster).CrossSubnetDelay= 4000 
    PS C:\Windows\system32> (get-cluster).CrossSubnetThreshold= 40 

    Try this too.

    Check your Backup System, if are starting bkp task for the Cluster and at the same time executing for VMs inside the cluster, that is one reason to lot your traffic at network adapter, cuz of that we change the heart beat time.


    Good Lucky

  • Seems like they finally solved it.

    Addresses an issue that occurs when using multiple Windows Server 2016 Hyper-V clusters. The following event appears in the log:

    “Cluster Shared Volume 'CSVName' ('CSVName') has entered a paused state because of 'STATUS_USER_SESSION_DELETED(c0000203)'. All I/O will temporarily be queued until a path to the volume is reestablished.”
