Hi,
This question goes out to you who are using Clustering in a production environment.
I wonder how stable it is? What issues have you had to overcome to get it stable? If you could do it over, what would you do differently?
Cheers!

I've had two problems with my MSCS SQL Server cluster since I installed it in October, 2001.
1, If you have a database job (such as a sp) that is a resource hog, there can be circumstances in which the sql server resource monitor failsover the server because it believes it is non-responsive. I was able to tune around this problem (with a lot of help from the third Microsoft technicial on the support call).
2, I had a problem with my Dell PowerVault 220S shared SCSI storage getting into a weird state and causing problems with delayed write operations which ended up causing problems with the cluster. I power cycled the dell, and it's been fine since then. My guess is a power line spike messed it up.
Anyway, apart from those two issues, it's been rock solid.
