disk image starting at a specific inode?

view full story

http://www.linuxquestions.org – Hi, I deleted some files on the command line and would like to learn if it's possible to recover them. It's not a terrible thing if they are gone, but I want to see what I can do. The server is configured as a hardware RAID5+1 (ext3, Debian Stable) and I *really* don't want to take a dd of the entire disk. ls -id gets me the inode value of the directory(155655) I'd like to create a disk image starting at that specific inode. Then there is the issue of picking an outer boundary of the disk image... I'm hoping there's a dd/ext3 genius out there to advise. (HowTos)
