I meant the other way around. If the two backup systems are "fried" but you can get their disks running on alternate "non-fried" systems, you can recover your data from those. > question: since I have a broken filesystem, does it even make sense > to make a disk image of it? or do you mean just for backup? (that if I > break it, I still have the broken stuff I started with?) Yes, it does make sense, and for the reason you surmise. Ideally you would get a disk image onto another system as an LV, take a snapshot of that, and then work with the snapshot. Then if things go awry, you just drop the snapshot and make a new one. If you're lucky, what's happened is that the /etc directory file has been damaged but that all of the objects it linked to are intact. fsck will reparent these objects under /lost+found if so. But there may be other damage as well. But even if you can't recover /etc, you may well be able to recover the data you're really interested in. And even if files have been orphaned and fsck doesn't reattach them under /lost+found you may be able to recover them using debugfs. _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
