1) Boot Fedora 19 x86_64 DVD ISO image from USB flash drive.
2) Select "Install Fedora 19" from grub menu
3) At anaconda language selection screen, wait for error to pop up.  Might have to hit tab after a while


Notes: I have 2 md raid arrays that have been in this system for years through various fedora installs and never had a problem.  They seem to get assembled OK, but then anaconda chokes on them for some reason.

I think my situation is different than the bugs in comment 14.  Note that I'm not trying to do anything fancy here.  Just booting anaconda in a machine that happens to have some existing md arrays in it.  I can't even get to the point where I choose an installation target device; anaconda gives the error before I can even get past the initial language selection screen.

I tried booting with raid=noautodetect added to the kernel command line, but anaconda still assembled the arrays and then got confused.

I do not even want to install to an md array. I just want to install to sda like I've done with the past 10+ Fedora releases.  Is there some way to get anaconda to ignore the arrays?  I really don't want some installer messing with my arrays unless I tell it to, anyway. Is there perhaps a new anaconda img without this bug?

My situation is similar to Matt, not installing to a raid array.
I have 2 raid1 arrays with /home of F17 and F18 mounted on them.

I was able to work around this by following the advice at https://bugzilla.redhat.com/show_bug.cgi?id=975811#c12 and adding a UUID label instead of /dev/md0 in the /etc/fstab of my existing install.

This is likely a dup of that bug 975811.

This is already fixed for F21 by commit 944ed1ee on blivet's master branch.
