Description of problem:
Setting up two different btrfs volumes for two internal disks on a laptop, shows both as having the same size of the first volume's disk.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have a laptop with two disks (typically SDD+HDD).
2. Go to custom partitioning, and click on automatic partitioning with btrfs (which creates one volume across both disks with two mount points, / and /home )
3. Deselect one of the the disks for the single volume, and create another volume with the other disk. Assign one volume for / and the other for /home .
Both mounts show as having the same space as the first volume's disk (in this case the SSD's size)
Each mount should show the space of their respective disk

At this time I don't know what the final state of the installated sizes are, as I never went through the install. The "questioner" at that link seems willing to test it, will update bug report with result.
According to the ask.fedoraproject.org link, removing the problematic mountpoint (/home) and creating it again, assigning it to the correct btrfs volume and manually sizing it fixes the problem.
Yep, and the related (original) issue of what Automatic partitioning does, or should do, when two drives are selected is a valid question. What's the expectation? I'd say for sure if the performance of the two drives is very different, then they shouldn't be combined in a single Btrfs volume. (The same thing happened with LVM+ext4 as the Automatic partitioning default.) Maybe it should put boot and sysroot on SSD, and /home on HDD.
