Anaconda malfunctions on an intentionally-broken RAID-1
Last modified: 2012-05-29 14:18:22 EDT
Description of problem:
When upgrading a system with a RAID-1 disk configuration, it is extremely useful to break the mirror before the upgrade, thus providing an instant rollback mechanism.
However, Anaconda has had an amazing number of malfunctions when presented with this kind of disk configuration.
As of the Fedora 17 install media, it simply fails to see the md devices.
Version-Release number of selected component (if applicable):
Fedora 17 release DVD (version unknown)
Steps to Reproduce:
1. Install an older Fedora system (I am currently using Fedora 15) on a pair of mdraid RAID-1.
2. Break the mirror by disconnecting one of the drives.
3. Boot Fedora 17 from media and try to do an upgrade to Fedora 17.
md devices are simply not seen, and so F17 insists on doing a new install.
Offer to upgrade an existing system.
Adding insult to injury, if one manually assembles and activates the mdraids in the Anaconda shell, Anaconda will "helpfully" *disabled them* on its own accord.
