From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; m18) Gecko/20010131 Netscape6/6.01 Description of problem: During an upgrade from RedHat 6.1 -> 7.1, anaconda reports an error (paraphrased) while trying to setup to read the old installation status: Raid device md0 needs 1 disks, but found 2. The raid device was created automagically by the original 6.1 installation. My fstab and raidtab are as follows: fstab: /dev/md0 / ext2 defaults 1 1 /dev/hda1 /boot ext2 defaults 1 2 /dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0 /dev/hdg1 swap swap defaults 0 0 /dev/fd0 /mnt/floppy ext2 noauto,owner 0 0 none /proc proc defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 raidtab: raiddev /dev/md0 raid-level 0 nr-raid-disks 2 chunk-size 64k persistent-superblock 1 device /dev/hda5 raid-disk 0 device /dev/hdc5 raid-disk 1 How reproducible: Always Steps to Reproduce: 1. Boot off RedHat 7.1 installation CD 1 2. Proceed with upgrade procedure Actual Results: anaconda reported an error and gave the option of debugging or giving up. Expected Results: anaconda should have mounted the raid array & proceed to scan the previous installation! Additional info:
Can you boot into your 7.0 system and post the output of the 'fdisk -l /dev/hda' and 'fdisk -l /dev/hdc' commands?

I guess my raidtab is wrong... But would this stop the installation?
Almost certainly. I can't imagine how the system worked in the first place. Please try again with a corrected raidtab and reopen this bug if this doesn't fix the problem.
