Hide Forgot
After creating two 1-Gb raid partitions in disks sda and sdb (one in each), I chose to create a Linux filesystem out of them, to be mounted in `/l', and named the device /dev/raid/l (I've also tried /dev/raid-l, without success). (Actually, I have created more than one partition in one of the disks, in one of my attempts, but I *think* I've also tried 1 parition per disk before giving up and setting up raid by hand after a regular installation). All was fine until the installation got to the point of creating the actual filesystems, just before packages start to be installed: I got an exception from the Python interpreter, and the installation was aborted. Please let me know if you need further information to duplicate the problem.
could you attach the text of the anaconda exception to this report ...? that would be helpful ... :)
That would be hard. I have already managed to create some raid devices, and I'd rather not mess up with them. Since I don't have any free disk space, and the problem shows up quite late in the installation process, I fear changes in the partition table may make it to disk before the failure, destroying the data I already have. Sorry, I should have noted the error message when I first got it, but I thought it would have been easy to duplicate, since I could do it so many times :-)
If you ever have a problem like this again please reopen this bug. We have not seen this behaviour in our testing so perhaps it was something specific to your setup.
