Symptoms
The message is reported during backup (VSS-Aware Microsoft Cluster Hyper-V backup sets)
"VSS: Specified path 'C:\CLUSTERSTORAGE\VOLUME-nr\' is on 'CSVFS' volume which does not support mount point.".
Cause
This is an expected information message, it is safely to be ignored.
Workaround
If the severity of the message is 'error' instead of information message, try to chage it as follows:
1. go to DS-User > Setup > Event Filter, click on the 'New' button.
2. In the box 'Event #:' type in or paste the corresponding message id:
0x4101001E
3. From the drop-down list available for the 'Category:' field choose 'Application'
4. From the drop-down list available for the 'Type' field choose 'Information', leave the already selected value for the 'Description' filed.
Save the changes to the Event Filter (click OK), then run the backup again.
