I just found a little bug in AlwaysOn. It’s actually not that big a deal, but it’s interesting. In a nutshell, if you have a table with an IDENTITY seed less than 1000, when you do a failover the table is reseeded to 1001. The steps to reproduce are posted on this Connect item. If you have feedback on this, please post it directly to the Connect item since I don’t think Microsoft reads my blog much.
