I'm looking for information on device-mapper, the kernel space utility for Logical Volume Management (LVM2). It seems that the relevant code resides under drivers/md and a lot of other information is under Documentation/device-mapper/ That's fine, but is there any other document that gives more finer details about the device-mapper. I've also recently subsribed to the device-mapper mailing list.

A nice diagram of the overall storage subsystem is at http://www.thomas-krenn.com/en/oss/linux-io-stack-diagram.html Dm is just a single block in it, but it can help to see where it fits in overall. Btw: that diagram doesn't show the legacy ata driver that creates /dev/hdx style devices. Has that been dropped while I wasn't paying attention? I haven't used it in years, but I thought it was still used on embedded systems. Greg -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.
