We got plenty off EventID 12289 and 8193 How to get rid off them?

Hi,

We have some problem with error messages in our Clustered Scale Out File servers in combination with Clustered Hyper-V environment.

We have 2 SOFS cluster with 2 host each.

Each Server is configured  with 2 Volume with 16,9 TB 

This Volume are shared in the Cluster as Cluster Shared Volumes  

And this share are shared to Hyper-V cluster and on this Shares we have the VM:s

The problem (error messages ) we got on the SOFS Servers is following

EventID 12289:

Volume Shadow Copy Service error: Unexpected error while calling GetStorageDependencyInformation. hr = 0x8007048f, The device is not connected.

.

Operation:

  Automatically choosing a diff-area volume

  Processing EndPrepareSnapshots

Context:

  Execution Context: System Provider

Error-specific details:

  Error: (0x8007048f) The device is not connected.

EventID 8193:

Volume Shadow Copy Service error: Unexpected error calling routine GetVolumePathName is fail on the path \\fasofs01.your.domain.com\vdisk01, winerror 0x0000007b.. hr = 0x8007007b, The filename, directory name, or volume label syntax is incorrect.

We got this error on every SOFS Host every day but different times.

And the amount off the error messages are different on the servers and the times too.

I have tried to find anything on the Internet but not find a good solution.

We use Veeam has a backup system and the backup seems to work from a Veeam perspective.

So what do we have to do to get rid of this errors

Best Regards
