In case you are trying to install a SQL Server 2008 R2 service pack in a clustered SQL Server environment and the installation fails reporting something similar to the below:
Final result: The patch installer has failed to update the shared features. To determine the reason for failure, review the log files.
Exit code (Decimal): -568706566
Exit facility code: 1562
Exit error code: 14842
Exit message: Element not found. (Exception from HRESULT: 0x80070490)
Start time: .....
End time: .....
Requested action: Patch
Then, the first thing you can do is to check if there are any disks in the cluster that are offline
. If this is the case, you need to bring the disks back online prior to trying again.
