Transaction rollback hanging from past two months(MSSQL 2016) I executed a query using SQLCMD on 2019-01-30, and the query caused ldf file to bloat exponentially and it became 2TB in size, then my MSSQL started rollback of transaction at 2019-02-01. I used KILL SPID WITH STATUSONLY to monitor the rollback process: progress of rollback was about 2% a day for first two weeks, afterwards the rollback process got stuck at 22% from 2019-02-14, and it's still there today.

I'd appreciate if I can get expert opinion on if there is any way to fix this issue - how to stop or speed up rollback? 

Please find below code details about this issue:



SQL

BEGIN TRAN
  DECLARE @m int
  SELECT @m = @@ERROR
  DECLARE @tbname_old varchar(50) = 'OTS_ARCHIVE'
  DECLARE @tbname_new varchar(50) = 'OTS_ARCHIVE2'
  DECLARE @column_old varchar(30) = 'GuID_ID'
  DECLARE @column_new varchar(30) = 'GuID_ID_old'
  DECLARE @sql varchar(50) = '[' + @tbname_new + '].[' + @column_old + ']'
  DECLARE @sqlid varchar(100) = 'CAST(CAST(NEWID() AS BINARY(10)) + CAST(GETDATE() AS BINARY(6)) AS UNIQUEIDENTIFIER)'
  DECLARE @date as datetime
  DECLARE @i int
  DECLARE @f int
  set @date = '2017-01-01'
  set @i = 0
  set @f = 27
  WHILE @i &lt; @f
  BEGIN
  EXEC ('INSERT INTO ' + @tbname_new +
    ' select
    GuID_ID
    ,Box_ID
    ,Start_Time
    ,End_Time
    ,Duration_Time
    ,ots_count
    ,Group_ID
    ,' + @sqlid + ' from ' + @tbname_old
    )
  END
IF @m = 0
  COMMIT TRAN
ELSE
  ROLLBACK TRAN
  SELECT 
    ERROR_NUMBER() AS ErrorNumber,
    ERROR_SEVERITY() AS ErrorSeverity,
    ERROR_STATE() AS ErrorState,
    ERROR_PROCEDURE() AS ErrorProcedure,
    ERROR_LINE() AS ErrorLine,
    ERROR_MESSAGE() AS ErrorMessage

After about 60 days, the rollback process was finally completed. It seems the only way and the only solution you should do is wait, wait, and keep waiting.
