So, dd finally sped up and finished. It appears that I have lost none of my data. I am a very happy man. A question: is there anything useful I am likely to discover from keeping the RAID array as it is a bit longer before I recreate it and copy the data back?

It'll be much helper for developers to collect kernel stack for all stuck thread(and it'll be much better to use add2line).


Presuming I can re-create the problem, let me know what I should do to collect that information for you. I'm very much a newbie in that area.

You can use following cmd:

for pid in `ps -elf | grep " D " | awk '{print $4}'`; do ps $pid; cat /proc/$pid/stack; done

Thanks,
