Hi everyone,
We are using fio to emulate the SPC-1 benchmark (we hope to get this
included as a --profile in fio in the not too distant future). However,
we have noticed that when running our benchmark the disk we are testing
does not seem to be overly busy seeking to different locations on the
disk. When we run tests using Iometer we can hear the disk seeking to
different sections of the disk pretty much the whole time. We are using
io_u->offset to define the position in the file we wish to read/write
at, but it is not clear to us whether this is having the desired effect.
It doesn't seem so at this point... We have been using the sync and
libaio engines.
Can someone please give us some advice to help us troubleshoot this
problem? Or point us to a tool that will let us see where fio is
reading/writing on the disk? Any help is greatly appreciated.
Kind regards, Mike
