Mount ContentDB

Question

I am mounting a contentDB to a 2013 web application (upgrading from 2010).
The contentDB size is around 2,5GB , the mounting process is stucked.
I checked in the log and it is stucked here:

InsertAllUserDataSparseDefaultRowOriginal Begin Upgrade()

The table AllUserData has around 5k records.
Any suggestions?

Answer 1

I had just to wait.
It tooks almost 2 hours.
It needs time to re-create the clustered index on the table. (in my case AllDataUsers table has more than 5k items)
