Yum upgrade from Fedora 14 to 15 lost software raid

[Farrow]

Hi guys

Been beating my head for the last two days, please help.

I used yum with the distro-sync param and all seemed to go well except when I rebooted. The boot stopped complaining it couldn't mound my two RAID0 drives. The distro is on a single drive and that is fine.

Basically cat /proc/mdstat doesn't show any raid setup and looking in /dev I don't see any md devices. When I run blkid I still don't see any md devices.

If I boot into a Fedora 15 rescue disk I can see the md devices and I can mount them perfectly so the RAID0 is still intact but I just can't get the block devices for them in my new upgraded installation.

Please help? Its like Anaconda isn't finding them? How can I resolve this? Looking on the net it looks like other people have had similar problems but I can't find a solution most people reinstall but I would like to avoid that if at all possible.

Thanks in advance.

Interesting Paul . . .

While I can't offer any specific help, I can give you my experience from Windows98 on through
to Linux Fedora (from F10 to the Fedora 16 Verne) and even Kubuntu and FreeBSD Unix . . .
(btw, I am a Fortran WATFIV user from college where my old Physics prof worked at JPL in Pasadena)

. . . so I am not a complete newbie to this sort of stuff -
(currently in Fedora 13 KDE - with rekonq as my web browser, as you can see from the icons under the post info)

Anyhoo . . .
I never, ever do an upgrade . . . too much of variable to the process of an installation, imho.

Anaconda sounds like a good enough reason -
but I always do a fresh, clean install rather than any upgrades
to avoid getting mired in just the sort of mess you may have.

Good luck . . .
. . . and welcome to Fedora forum.

Thanks Jenaniston.

Having just read "Upgrading Fedora using yum" and skipping directly to the F14 -> F15 bit and not reading the WARNING about upgrading via YUM as not supported will teach me to read everything before jumping straight in !!! I guess I will try to upgrade from 15 to 16 now using the DVD and hopefully Anaconda will detect my RAID drives as it does via the rescue option of the Fedora 15 dvd. I guess if all else fails I will have to restore from my backup.

If any one else has a comment before I do that on how I might get my md RAID devices to show up, I would appreciate it.

Thanks

I have a RAID-1 running Fedora 16 and would like to upgrade to Fedora 17. After downloading the DVD and booting it, the installer only gives me the option to overwrite my installation. It does not recognize my RAID configuration either.

Guess I'll be sticking with Fedora 16 for a while.
