Description of problem: I tried to switch my Volume Group to use RAID1 on just the first two disks and Anaconda crashed. The following was filed automatically by anaconda: anaconda 19.28-1 exception report Traceback (most recent call first): File "/usr/lib/python2.7/site-packages/blivet/size.py", line 80, in _parseSpec raise ValueError("invalid size specification", spec) File "/usr/lib/python2.7/site-packages/blivet/size.py", line 138, in __new__ self = Decimal.__new__(cls, value=_parseSpec(spec)) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/lib/accordion.py", line 61, in selectorFromDevice size = Size(spec="%f MB" % device.size) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/custom.py", line 1033, in _replace_device selector=selector) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/custom.py", line 1314, in _save_right_side selector=selector) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/custom.py", line 2746, in on_apply_clicked self._save_right_side(self._current_selector) ValueError: ('invalid size specification', '-30708.000000 MB') Version-Release number of selected component: anaconda-19.28-1 Additional info: reporter: libreport-2.1.4 cmdline: /usr/bin/python /sbin/anaconda cmdline_file: initrd=initrd.img inst.stage2=hd:LABEL=Fedora\x2019-Beta\x20x86_64 quiet BOOT_IMAGE=vmlinuz executable: /sbin/anaconda hashmarkername: anaconda kernel: 3.9.2-301.fc19.x86_64 product: Fedora release: Cannot get release name. type: anaconda version: 19-Beta Truncated backtrace: Traceback (most recent call last): File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/custom.py", line 2746, in on_apply_clicked self._save_right_side(self._current_selector) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/custom.py", line 1314, in _save_right_side selector=selector) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/custom.py", line 1033, in _replace_device selector=selector) File "/usr/lib64/python2.7/site-packages/pyanaconda/ui/gui/spokes/lib/accordion.py", line 61, in selectorFromDevice size = Size(spec="%f MB" % device.size) File "/usr/lib/python2.7/site-packages/blivet/size.py", line 138, in __new__ self = Decimal.__new__(cls, value=_parseSpec(spec)) File "/usr/lib/python2.7/site-packages/blivet/size.py", line 80, in _parseSpec raise ValueError("invalid size specification", spec) ValueError: ('invalid size specification', '-30708.000000 MB')

I created my virtual machine with 6 disks and I selected all 6 of the disks at the "Installation Destination" spoke. I chose LVM and told it I want to review the partitions. I clicked the link to create the automatic layout. I selected the / filesystem and clicked the "Modify..." button for the "fedora" Volume Group. All 6 disks were selected, but I changed it to just the first 2 disks. I chose a RAID1 setup and hit Save and Update Settings and a few seconds later Anaconda crashed with the error about the negative disk size.
