*************************
We restart VSS and COM+ services, and event reboot the server, but the problem persist. Also re-register the VSS DLL files, later reboot, and same results.
The last test, was evict the node from the cluster, and here, there is no errors.
When add to the cluster, the errors begins:
Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{a26fb4bd-c4de-437c-84a8-4d5a3cf6022f} - 00000000000003B0,0x00530024,0000000000000000,0,0000008F0D350080,4096,[0]). hr = 0x80070001, Incorrect function.

.
Operation:

Error-specific details:

**************************
Also was executed a Windows Server Backup with the host out off the Cluster, ant the same fails with the error:
The backup operation that started at '2020-04-06T19:57:09.907735000Z' has failed with following error code '0x807800C5' (There was a failure in preparing the backup image of one of the volumes in the backup set.). Please
review the event details for a solution, and then rerun the backup operation once the issue is resolved.
Some experience or suggestion?
