To reproduce: 1. Start with two empty disks 2. Boot the 2015-07-17 nightly boot.iso 3. Select both disks as targets and go to custom partitioning 4. Add a 200M /boot partition 5. Attempt to add a 2GB swap partition Result: a red bar 'Failed to add new device. Click for details.' Clicking the bar shows an error: "invalid value NotImplemented for size".

The /boot partition isn't necessary, but the two disks *are* necessary. I can reproduce with these steps: 1. Start with two empty disks 2. Boot the 2015-07-17 nightly boot.iso 3. Select both disks as targets and go to custom partitioning 4. Attempt to add a 2GB swap partition But not like this: 1. Start with one empty disk 2. Boot the 2015-07-17 nightly boot.iso 3. Leave the disk selected as the target and go to custom partitioning 4. Attempt to add a 2GB swap partition
Something very similar happens if you do this: 1. Start with two empty disks 2. Boot the 2015-07-17 nightly boot.iso with an updates.img containing all changes to current git master for anaconda and blivet 3. Select both disks as targets and go to custom partitioning 4. Click 'create them automatically' 5. Select the / partition, change its type to RAID 6. Click Update Settings This causes the usual 'An unknown error has occurred' dialog to pop up (not a red error bar), but with the same trace: "invalid value NotImplemented for size". I filed a libreport bug for that case: https://bugzilla.redhat.com/show_bug.cgi?id=1245854 .
Yep, this turns out to have the same underlying cause as 1245854, which has better logs and info, so closing this one. I figured out the cause and have posted a fix. *** This bug has been marked as a duplicate of bug 1245854 ***
