Hi, Can you please try again, get as far as you can without problems, and then switch to tty2 (CTRL + ALT + F2), and collect all the log files under /tmp and attach them here ? (you can use for example scp to get the log files out of the installer environment). Thanks, Hans Hmm ... I've already managed to perform the upgrade as per the additional comment I posted on: http://forums.fedoraforum.org/showthread.php?t=241373 > The problem is that the Fedora 12 installer (unlike the previous ones) does not > start the RAID1 arrays prior to scanning for live systems.

Hopefully the installer will not see the upgraded system since it doesn't enable the RAID1 disks so I'll be able to reproduce the problem for you. Created attachment 397711 [details]
Collected log files
Attached are the requested log files. These were collected immediately following the "Detecting storage devices" (or similar) screen and while the installer was waiting for the hostname to be entered.
Ok, so here is what anaconda sees on your system: /dev/sda1 mdraid partition /dev/sda2 mdraid partition /dev/sda3 swap partition /dev/sda4 mdraid partition /dev/sdb1 EFI vfat partition Are you using raid1 sets in degraded mode (iow mirrors with only one disk present) ?

Yes. When doing an upgrade, I split the RAID1 pair for backup purposes. This way I have a fall back position should the upgrade fail. As I explained in the description, this strategy worked well for my upgrade to FC10 and I was extremely surprised to have such difficulty getting from FC10->FC11 or FC10->FC12. Hi, Our official policy is that doing installs / upgrade on degraded raid sets is not supported. This has always been the case, if upgrades on degraded raid happened to work in the past that was mostly luck. So I'm going to close this bug as notabug. If you would like to see this changed, please file a new bug with as summary: "RFE: Allow use of pre-existing mdraid sets in degraded mode" Thanks, Hans Created attachment 398224 [details]
Collected log files with singleton RAID1 sets
I decided to try another approach.
Rather than run a degraded RAID1 set, I re-configured the RAID1 sets to be singletons:
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] [linear]
md3 : active raid1 sda4[0]
265666816 blocks [1/1] [U]
md0 : active raid1 sda1[0]
8385792 blocks [1/1] [U]
md1 : active raid1 sda2[0]
39061952 blocks [1/1] [U]
unused devices: <none>
Thus these are no longer degraded RAID1 sets.
I've re-opened this defect because the FC12 installer would not
recognise this non-degraded configuration.
It recognized your singleton arrays just fine. It's just that we can't upgrade from Fedora 12 to Fedora 12. From the logs: INFO: product Fedora version 12 found on md1 is not upgradable It would be great if you'd post your solution to the forums, BTW.

From the logs: > > INFO: product Fedora version 12 found on md1 is not upgradable ROTFL I'll try an FC12 -> FC13 upgrade to verify that it indeed does make an effort to begin the upgrade before posting this workaround. It will be a couple of days before I have time to verify this. (In reply to comment #9) > It will be a couple of days before I have time to verify this. Ok, I've verified that the FC13-alpha installer will see a RAID1 singleton and offer me an option to upgrade.
