Hi all,
anyone with an update on these two questions?
I was thinking to use the kernel block trace facility to track disk
access and infer the on-disk data structure, but I haven't tried for now.
On the other hand, I carefully looked at mdadm output, without finding
anything related to physical block placing.
Any new advices on that regard?
Thanks.
