Bug Description

Binary package hint: laptop-mode-tools

When the filesystem is on a raid device, lm-profiler only reports disk access by a process called md0_raid1 (the md module).

Unfortunately, this information does not help in identifying the processes that actually causes the disk access.

Thank you for the link.

I found out about block_dump, and unfortunately, that laptop_mode seems to gets into a resyncing loop with raid devices.
Hopefully, has there bin some progress in resolving that?

Concerning the bug reported, maybe lm-profiler could look at the writes to the md or lvm devices as well as to the physical devices?

 I'm not sure but I think we just make use of what the kernel provides.
I'll still check though.
