| I'm a bit lost about the Lost and Found directory. (BTW - new to Linux and Sarge.) I have tried to find out what it's for and what needs to be done with it - but without much success. Perhaps some kind soul could give a simple explanation - or point me to one? -- Chris |

Perhaps some kind soul could give a simple > explanation - or point me to one? Many (but not all) filesystem types use it for filesystem recovery. Most notably when checking the filesystem, if they find stuff which still exists (e.g. non-zero length file with non-zero link count) but doesn't have a proper place (exists in no directories), since the recovery may know the file structure and it's associated data, but not where it should be located, or what link name(s) it had, the typical recovery process (fsck) would place it in the lost+found directory at the root (topmost level) of the particular filesystem in question. For the applicable types of filesystems, the lost+found directory should exist, its permissions should not be mucked with (that could create security issues), and it should not be removed (if it is removed, care should be taken that it is created to be of appropriate size). The reason lost+found must exist and be of appropriate size when doing such recoveries, is that the recovery process may need a directory to link found stuff into - and if there's a fair amount of stuff found, it will need enough existing empty slots in the directory to link things there without growing the directory (as growing or creating the directory while trying to do a recovery could potentially destroy data one needs to recover - or at best would greatly complicate the recovery process - and there's also risk that the filesystem could be or become full, and again it would then be impossible or infeasible to reasonably conveniently recover the data/files). Other suggestions. Start here: http://www.catb.org/~esr/faqs/smart-questions.html do the basic STFW exercises if you haven't already, e.g.: http://www.google.com/search?hl=en&q... Google+Search and read at least some of the relevant stuff (if you haven't already) and ask more specifical questions - e.g. asking what you still don't understand or where you're getting confused by what (potentially confusing, conflicting, or incomplete) stuff you've read. Also, folks aren't going to reply to your e-mail if it's bogus. In many cases folks might bother to reply via e-mail if they think their reply might be useful or informative to you, but may not be sufficiently noteworthy to bother to post on USENET. If your e-mail is bogus (or bounces) in such cases, you might miss out on useful replies/information. |

Perhaps some kind soul could give a simple > explanation - or point me to one? You don't have to do anything with it. You can pretty safely ignore it. The file system will, from time to time, throw lost files in there - doesn't happen often. |
