Hold on. I think I found the culprit here. I was thinking that what is
the difference between two setups and realized that with vanilla kernels
I had done "make defconfig" and with io-throttle kernels I had used an
old config of my and did "make oldconfig". So basically config files
were differnt.
I now used the same config file and issues seems to have gone away. I
will look into why an old config file can force such kind of issues.
So now we are left with the issue of loosing the notion of priority and
class with-in cgroup. In fact on bigger systems we will probably run into
issues of kiothrottled scalability as single thread is trying to cater to
all the disks.
If we do max bw control at IO scheduler level, then I think we should be able
to control max bw while maintaining the notion of priority and class with-in
cgroup. Also there are multiple pdflush threads and jens seems to be pushing
flusher threads per bdi which will help us achieve greater scalability and
don't have to replicate that infrastructure for kiothrottled also.
Thanks
Vivek
