Getting erroThe system failed to flush data to the transaction log.

Question

Hi Experts,

I have a two node cluster (both windows 2016 datacenter) version.
In the current owner node I got the below alert yesterday

Cluster Shared Volume 'Volume1' ('Cluster Disk 1') has entered a paused state because of 'STATUS_DEVICE_BUSY(80000011)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Cluster Shared Volume 'Volume1' ('Cluster Disk 1') is no longer accessible from this cluster node because of error '(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.

The system failed to flush data to the transaction log. Corruption may occur in VolumeId: Shared Backup, DeviceName: \Device\HarddiskVolume26.
({Device Busy}
The device is currently busy.) event id 140.

There is no change done by me on the server. This errors were present in server for atleast 1 hour. In this time period the app team were not able to do I/O in the disk which is the only CSV. Later they were automatically able to write in the drive.

Any help for this would be appreciated.

Now the above events are not getting triggered but a new warning is in cluster events in every 15 minutes.

Cluster network name resource failed registration of one or more associated DNS names(s) because the access to update the secure DNS Zone was denied.
Cluster Network name: 'WMDPP01Databases_SANA-WMLSNRPP01'
DNS Zone: 'am.corp.airliquide.com'
Ensure that cluster name object (CNO) is granted permissions to the Secure DNS Zone.

Please provide suggestion for this as well.
