I just attempted installing Update 1 on our TFS 2012 server. The installation made me run back through the configuration wizard. I received the below error during the upgrade of our primary project collection:
[Error] The index 'PK_WorkItemsAre_Sparse' could not be created or rebuilt. A compressed index is not supported on table that contains sparse columns or a column set column.
In speaking with our DBA, he sees that the upgrade dropped the PK for the table, so it looks like the process is trying to recreate the PK and receiving this error. The rest of the update finished and now I am left with a project collection that is offline and will not complete the servicing job that is queued up for it.
What should I do next?
