I have a separate 3T ESATA removable hard drive I use for backups. I can see it from where I sit. But you apparently know better than I do what I have in my house. Quite a remarkable feat from many thousands of miles away. Why do you presume I'm such an idiot? I know how to recover from backups. I probably did my first recovery from backups before you started elementary school. I've designed, written, deployed and managed fully automated backup systems - written disk drivers, SCSI chip drivers, tape drivers, tape jukebox drivers, file systems, btrees. I've never written disk firmware, but I've written code at every level above that. Yeah, I think I know about backups. I can avoid recovering from backups, since I don't have any data I care about in the bad blocks. But I do back up a few times a day at this point in time ;-) and I'll back up one more time just before I shut down to replace the drive (with the replacement that arrived today). The fault tolerant dd ideas are more interesting than a simple restore, since they preserve the bit maps, and inode numbers, are compatible with the other mirror copy and so on... I addressed the list so I could learn what DRBD is supposed to do in these circumstances, to see if I had some settings wrong, and also suggest what it /could/ do. A couple of DRBD features came from my suggestions in the past (as Phillip or Lars could tell you). Not all my ideas are equally good, but sometimes they work out. -- Alan Robertson <alanr at unix.sh> - @OSSAlanR "Openness is the foundation and preservative of friendship...
