Comment 28 for bug 875343

I've just been able to reconfirm the problem with both the server and desktop installs. Interestingly on the server install I get an actual failure, but on the desktop install it hangs as per the bug description.

My setup was / on /dev/sdb1 (part of a pre-created btrfs raid1 array) and /var on /dev/sdb3 (part of a second array). I indicated that /dev/sda1 and /dev/sda3 were / and /var, respectively. I asked the partitioner not to format the drives.

Mounting / and creating /var, worked fine for me as a workaround.
