> I’ve heard conflicting asserts on whether the write returns with min_size shards have been persisted, or all of them. I think it waits until all replicas have written the data, but from simplistic tests with fast network and slow drives, the extra time taken to write many copies is not linear to what it takes to write the first, so unless you do go min_size=1 (not recommended at all), the extra copies are not slowing you down as much as you'd expect. At least not if the other drives are not 100% busy. I get that this thread started on having one bad drive, and that is another scenario of course, but having repl=2 or repl=3 is not about writes taking 100% - 200% more time than the single write, it is less. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
