During installation of a new SQL Server 2008 R2 clustered instance, all of the active 2008 R1 instances on that node failed. The error logs tell me that the services for those three instances failed, but there isn't any additional information about the cause of failure.
Note that this would have been the first R2 instance on this cluster. The OS is Server 2008 R2. Also, the initial attempt at installation was halted because of a pending reboot. We rebooted these servers over the weekend, but post-installation (and failover) we still see a message that a reboot is required.
I speculate that the R2 installation touched some shared DLLs that caused the R1 instances to fail on the active node, but I haven't seen any indication of this in the Windows logs. Has anyone run into this before? Yes, this was a production system, and this happened during normal business hours.
Thanks for your help.

I'm assuming you mean SQL server 2008, there is no R1.

check the cluster events and the Windows application log carefully.

The only shared DLLs will be for the client tools. It's perfectly feasible to have instances of different sql server version on the same system.
