Hi all,
I'm new to MD RAID. When I read the book "Understanding the Linux Kernel", I know that there are several layers between Filesystems (e.g. ext2) and block device files (e.g. /dev/sda1). These layers are:
Filesystem <==> Generic Block Layer <==> I/O Scheduler Layer <==> Block Device Driver <==> Block Device.
May I know where exactly is the MD RAID Device Layer(e.g. /dev/md0)?
Thanks a lot!

MD lies between "Generic Block Layer" and "I/O Scheduler Layer".
