With a relatively small database I enabled Transparent Data Encryption. From SQL server I queried the status of the encryption using this SQL command
select * from sys.dm_database_encryption_keys
The database, after several hours, showed 0 percent complete and encryption state of 2 (not 3). No problem, I went away for nearly a week and returned to check the status again. It hasn't changed! Both the azure portal and SQL report 'in progress'. I ran DBCC CheckDB() which found no issues.
Has anyone run into this situation? Is there something else that needs to be done to get this going and completed?
