Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am using Debian etch. I have raid1 on /. While running mdadm-raid, I see failed(busy). While running umounting fs, I see /dev/md0 still in use. How can I fix this problem and umount it correctly while running shutdown or reboot? Here is my rc6.d:
when you remount a filesystem in RO mode, the kernel automatically flushes the buffers to the drive. so when the drive is in read-only mode, no harm can be done to the filesystem. it means no more writing so no harm.
there's no doubt that almost all process uses /. i don't know which process to kill too. can't you just remount your fs in ro mode then try to kill the processes you can?
sometimes shutdown scripts goes to this procedure:
first send all processess the terminate signal (kill -15).
then send them the kill signal (kill -9).
the kernel processes remains and it's now safe for system shutdown.
These commands are unknown - kill -15 and kill -9. Kill gives me help how to use it. But I think, there is no problem, because there is sending all processes the term signal and then kill signal when rebooting.
