:Hi,

:What if your box is running in a production env where it is doing IO
:24/7 365days a year. Is stopping at any time to do a load of IO really
:that acceptable ?

Well, it wouldn't be stopping. And yes, it is. Think of it as
deferred maintainance. You are controlling when to do it rather then
building it into each operation.
Ultimately we want to have an I/O scheduler to have even more control.
Right now the hammer utility can be told to run for only a specific
amount of time, for example like 5 minutes a night, and that seems
to be an ample control.
