Question,
I am wanting to run a cluster on the main table in all of our 200+ databases. However, my manager wants to know what would happen if we suffer a major failure while the cluster is running. If I am running a "cluster chosen_index on main_table", and the server crashes, would the database come back up (assuming the crash did not corrupt the database drives), or would I be looking at a restore and roll forward?
I am very confident in the cluster, and have seen it improve our performance, but my boss is still a bit cautious after all the server issues we had on our old servers and I don't know for sure the correct answer. I believe that the database would self recover like it does 99% of the time, and we would be back up running in a few minutes, but I need to know for sure.
So, what am I looking at if there is a major failure in the middle of a cluster operation?
Thanks,
Chris
