Hi again, coming back to my problem with the inode of my home directory having disappeared, I found out that the tool ffs2recov from the ports is able to establish an inode entry for a directory where you can explicitely name the inode and the directory. I know which inode number my former home directory had, and of course I know its name. Would it be sufficient to % fs2recov -c 12345 -n poly ad0s1f.dd I think there's more to establish an intact directory structure. As far as I've already learned, when "walking back" the path from a file deep within a directory structure, every inode contains a field "where it comes from", let's say, where CWD and .. are (as an inode number): bla.txt dingens/ foo/ poly/ / 12380 -----> 12370 -----> 12360 -----> 12345 -----> 2 This would be /home/poly/foo/dingens/bla.txt on ad0s1f (where / is then mounted as /home). When I can assume that every inode still knows "where it came from", what would be a useful tool to build poly/ (12345) again? I think I'll need to construct its content again, because just by creating poly/ as 12345, where does the filesystem know from what's the content of poly/? Is the term "directory slots" I came across related to that topic? Which sources could give good hints? Sadly, fsck_ffs doesn't do the job... but maybe if I fix the file system a bit (instead of fixing fsck_ffs)...? Hey, it's not that I try to build my own nuclear plant in the living room... :-) -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
