    What did vdbench write

    2680354

      Hi Gurus,

       

      I see that DV issues start raising endless questions from several teams and overtime. I guess one of the easier way to answer many questions is if knew what was going on. I know that vdbench keeps an in-memory map of what it had written where. Is there a way vdbench can dump this map in logs when it encounters any error?

          Basically, it will be helpful to know what data vdbench wrote where....

            Hi Henk,

            I noticed that in one of my test runs vdbench reported following DV error. Is there a way to verify that vdbench actually wrote this data ?

            Error log. If there is no data beyond this line then there were no Data validation or I/O errors.

              Judging what Vdbench has printed at the LEFT, reporting Data Validation key 0xb '0x010 0b..0000', Vdbench has written this block 10 times, using keys 1-10. (Ignoring the fact that it possibly could be 10+126, 10+252, etc due to key roll over)

              On the RIGHT is is printing what it found, and that data clearly has not been written by Vdbench, note how repeatable that data pattern is and is not created by Vdbench.

              Are you sure nobody else was writing to this same volume?

              I see you were using the '-vt' (timestamp) option which tells you that the last time this block was valid was at 'Fri Jun 13 02:15:36 PDT 2014'. This was the time the block was last successfully written.


              Hope this helps,


              Henk.

                Thanks Henk that was helpful. This thread was to basically find out if there is a log/checksum that vdbench stores to figureout what it wrote and where ?

                Can we find out if vdbench had earlier written this which it matches with the read data ?

                Is there a way to figure out that vdbench had written data on left from a log or somewhere?
