I have installed SQL Server 2019 CU 2 over a vanilla install of SQL Server 2019 RTM.
Now I am puzzled by the following messages in the error log at startup:
RecoveryUnit::InitPersistentVersionStore failed with db  name [master] RecoveryUnit::InitPersistentVersionStore failed with db  name [msdb]
AFAIK the PersistentVersionStore links to the new feature Accelerated Database Recovery however I have not configured it.
The error occurs again after a service restart.
Is it automatically enabled with CU2 for system databases? Is there anything I can do about this error in order to resolve it?
I already did a web search with the error message but most surprisingly didn't find anything regarding to it.
Quick update (March 16th):
- Opened a Ticket with Microsoft Support (no answer yet)
- Installed SQL Server 2019 CU 3: Error persists at service restarts just as with SP 2
