get_stats() on pool gives wrong number?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a RADOS pool with nearly a million objects in it--but I don't exactly know how many, and that's the point.

I ran a long list_objects() overnight and, at first glance this morning, the output looks good, but it is thousands of objects fewer than get_stats() said are there. I am just doing early development and this cluster isn't deployed in any production, so I seriously doubt there is any other activity going on changing the total. (I know *my* code isn't doing anything--it is broken by this mismatch.)

A few weeks ago I learned that get_stats() can be out-of-date and report low, that it takes time for news of new objects to arrive, and that makes sense. But can get_stats() also report high (by over 1%)? Is get_stats() just a ballpark estimate?

Thanks,
