1) installed 0617.0 rhel6 nightly where the root partition is md0 raid over 2 raid partitions, each 3 GB
2) ran 0615.1 rhel6 installer. The crash occurs during 'examining storage devices' step.

Comment 5 Chris Lumens 2010-06-18 15:00:40 EDT
Is /mnt/sysimage still mounted when you hit this error message?  I see that it tried to run mount and then immediately after run umount, but there's no errors listed.  Perhaps the unmount failed?
Comment 6 Ales Kozumplik 2010-06-21 08:39:34 EDT
hmm. I am unable to reproduce it today, but I can not think of anything that is different

Let's close this and see if I someone runs into it again.
