In the long term, I would think we can add a common library for threads-pool,
we have several modules having their own implementation of threads-pool(ptlrpc
service has two threads pool, LNDs...), so if we have such a library (create
threads, kill threads, grow threads, shrink threads) then we
That could be awful handy - especially when trying to tune a live file system
for performance. Is that going to be a 2.0 only enhancement or can it be
applied to existing 1.8 versions?

Quick question: Has runtime modification of the number of OST threads been

Yes, see bugzilla ticket 18688. It was landed in 1.8.1.

However, I don't think you can decrease the number of running threads.
See https://bugzilla.lustre.org/show_bug.cgi?id=22417 (and also

I'm inclined to agree. So apparently the only time that modifying the runtime
max values has a benefit is while the threads_started is low?

Yes, this can be set at startup time to limit the number of started threads.
There is a patch I wrote to also reduce the number of running treads but it
wasn't landed yet.
