Description of problem: I'm attempting to upgrade from Fedora 8->9 and am running into a problem. The installer complains about multiple devices on the system having duplicate labels. I can see this when I run blkid.... /dev/sdb1: UUID="f64f73ae-a7b8-c3f3-c99b-51f87ca65c04" TYPE="mdraid" /dev/sdc1: UUID="f64f73ae-a7b8-c3f3-c99b-51f87ca65c04" TYPE="mdraid" /dev/sdd1: UUID="f64f73ae-a7b8-c3f3-c99b-51f87ca65c04" TYPE="mdraid" /dev/sde1: UUID="f64f73ae-a7b8-c3f3-c99b-51f87ca65c04" TYPE="mdraid" However, since all four of the above partitions are members of md0, a RAID-5 Linux software RAID device, I can't change the UUID or set a label using the usual tune2fs/e2label programs. In fact, it seems as though they're supposed to have the same UUID - I'm not sure on that though, running mdadm -E on each yields a different (but still common across all 4) UUID. Regardless, this causes the installer to fail miserably. Any workaround would be appreciated - either a way to change the UUID on a block device lacking a filesystem (part of a software raid array) or to get the installer to ignore the fact that the UUID's are identical.
I discovered the problem. The partition type must be set to "Linux raid auto" for anaconda to allow duplicate UUID's. This is different from earlier versions of Fedora, but I think the problem can be considered to be on my end. Sorry for the trouble!
