I did try an upgrade install, but a damaged yum/rpm database file really confused the upgrade logic. That left me with a half fc5 half fc6 system that had non-working xterms. I didn't really expect it to work, I was just curious what would happen. After that, I did poke at the fs a bit from the rescue mode on the install dvd, and then it hit me I really only had vg00 on the first disk and the other vg spaning the other 3 disks. I could safely do a clean install on the first disk leaving the other 3 disks untouched. > Why must the FC5 bits get nuked? I didn't get what the driving force > for the effort is. A few months ago I did a "yum -y update ; shutdown -r now". I don't know if the yum database needs a few 10's of seconds to get flushed cleanly, or what, but it got royally scrambled. A "yum list" after the reboot showed that the set of *.db files was corrupted. I could rebuild some of it from the yum cache directory, but roughly 1/3 of the rpm headers (~400) were no longer in the cache. Nuking all of fc5 would be a good way to make sure that everything in the filesystem is accounted for with no stragglers. > Well without a backup your data is in a fragile way anyway.

Its a combination of machine generated data and crap loaded from the net, so losing it wouldn't be the end of the world. In the past I've always bought a newer bigger disk whenever I installed a new OS. I also used to unplug the old disks just to prevent mishaps during the install. I'm still waiting for price parity before I pick up one of the 750GB ones. They still want $100 too much vs. buying 3 of the same series drives populated with 250GB worth of heads and platters. -wolfgang -- Wolfgang S.
