Thanks for the reply.
now based on your advise, if my participation is confirmed, by march,
I would come up with a concrete proposal or an experimental code
to share results at the conference if needed.
Thanks, Anand

Hi,
I'm replying somewhat late but when going through attend requests I was

Hot spare: is an important feature for the data centers. Hot spare
feature is common to MD, LVM and btrfs. And each of it locks in
resource to be used only at the event of failure. A system running more
than one type of VM like LVM and btrfs would end up having hot spares
assigned to each of the different VMs which looks system under
utilized.
So to increase the utilization of disk hot spares with in the system,
a common kernel module with API could do a job better, with some
additional features.
If needed I can provide a shot talk (just talk no slides) so to obtain
feedback and comments from the experts and have discussions.
Do you have a concrete proposal or even patches for the module? Because I
guess the general idea is fine but the issue may be in how should we
exactly tie into LVM and btrfs. So without the details there won't be
much to discuss...
