In this case, I'd say that it's more likely that dm-crypt is to blame rather than MD. I think you should try the dm-devel mailing list. Posting a complete log of everything that has happened would probably be a good thing. I have no experience with dm-crypt, but I do have experience with another dm target (dm-snapshot), which iss very good at destroying my data. If you want a stable solution for encrypting your files, I can recommend loop-aes. loop-aes has very well thought-through security, the docs are concise but have wide coverage, it has good backwards compatibility - probably not your biggest concern right now, but it is *very* nice to know that your data is accessible, in the future as well as now - etc.. I've been using it for a couple of years now, since the 2.2 or 2.4 days (can't remember), and I've had nothing short of an absolutely *brilliant* experience with it. Enough propaganda for now, hope that you get your problem solved :-). - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
