I was installing F 9 from live CD to oldish i386 athlon machine. My situation is as follows. I have two disks, sda and sdb. sdb is "new" disk, I have had sda before that. For that reason, sda contains several partitions that used to serve purposes of /boot, swap, and /. Nowadays I use sda as /boot, swap and /home, while having / on the "new" disk, sdb. /home partition is pretty aged reiserfs, the rest are ext3 partitions (and swap). What I did when presented with disk layout dialog was that I requested detailed view (sorry, forgot how is it called exactly). There I assigned sda1, sda2 and sda3 respectively to /boot, swap and /home. I allowed reformatting of sda1, but not of sda3 (obviously). It bothers me a bit that anaconda tried to run reiserfstune even though I asked it not to mess with that partition, but there could have been legitimate reasons for that. I assigned sdb solely to / (which is to say that there was single partition sdb1 on that disk), and asked anaconda to reformat it. Then I hit next, and anaconda thrown the exception. I tried the whole process three times total, each time reducing the amount of my tinkering. In the end I just didn't use detailed view at all, and just ticked out sda and let anaconda do its magic. This worked. I will attach the two fail logs that anaconda spewed.
Created attachment 310003 [details] First fail log.
