  • 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?

  • 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.
