Here is the official documentation for it: http://www.debian.org/releases/stable/i386/ch08s07.html.en But that is fairly terse. Let me say that the rescue mode looks just like the install mode initially. It will ask you keyboard and locale questions and you might wonder if you are rescuing or installing! But it will have "Rescue" in the corners so that you can tell and be assured. Get the tool set up with keyboard, locale, timezone, and similar and eventually it will give you a menu with a list of actions. Advanced options... Rescue mode keyboard ...starts networking... hostname domainname ...apt update release files... ...loading additional components, Retrieving udebs... ...detecting disks... Then eventually it will get to a menu "Enter rescue mode" that will ask what device to use as a root file system. It will list the partitions that it has automatically detected. One of the menu entry items near the bottom will be "Assemble RAID array". That will bring up the next dialog menu asking for partitions to assemble. Select the appropriate for your system. Then continue. That should produce an additional set of listings for the lvm volumes on your system including the root logical volume. Select it. At that point it presents a menu "Execute a shell in /dev/...". That should get you a shell on your system with the array mounted. Hopefully that will get you back to a point where you can then debug and recover your system fully. It isn't done yet. But it is in recovery mode at that time. Good luck! Bob
