This (from the anaconda backtrace) makes me think that it's getting confused by the IMSM (Intel BIOS RAID) metadata device: MDRaidError: name_from_md_node(md126p1) failed Local variables in innermost frame: node: md126p1 md_name: md127 name: None link: imsm full_path: /dev/md/imsm md_dir: /dev/md I did some playing around with running "anaconda --askmethod" from a live CD, and the results were ... interesting. At first, I got the expected crash, so I edited /usr/lib/python2.7/site-packages/blivet/ devicelibs/mdraid.py and added some additional logging to both name_from_md_node and md_node_from_name. Just to ensure that the updated version was used, I also deleted the mdraid.pyc and mdraid.pyo. Once I did this, the crash went away. This suggests a couple of different root causes to me: 1. There was something messed up about the pre-compiled files. 2. (Far more likely) some sort of race condition with udev. Partitions on top of MD RAID seem to take a particularly long time for all of the helper programs to run, so perhaps udev simply isn't finished creating all the symlinks that anaconda needs (until I slow anaconda down by adding the logging and/or removing the pre-compiled files). *** This bug has been marked as a duplicate of bug 1160424 *** |
