+++ This bug was initially created as a clone of Bug #1027682 +++ Description of problem: I went to custom partitioning, there was a previously installed encrypted F20 installation. I unlocked it. Then I re-used old swap and /boot partition in the new layout. I deleted old /home partition and reused old / partition. The / partition was marked as reformat and also enlarge from 50 to 60 GB (I had free space because I deleted /home). Anaconda crashed during the first stage of installation. Version-Release number of selected component: anaconda-20.25.6-1 The following was filed automatically by anaconda: anaconda 20.25.6-1 exception report Traceback (most recent call first): File "/usr/lib/python2.7/site-packages/blivet/devices.py", line 810, in _preDestroy raise DeviceError("Cannot destroy non-leaf device", self.name) File "/usr/lib/python2.7/site-packages/blivet/devices.py", line 2715, in _preDestroy StorageDevice._preDestroy(self) File "/usr/lib/python2.7/site-packages/blivet/devices.py", line 2734, in resize self._preDestroy() File "/usr/lib/python2.7/site-packages/blivet/deviceaction.py", line 403, in execute self.device.resize() File "/usr/lib/python2.7/site-packages/blivet/devicetree.py", line 237, in processActions action.execute() File "/usr/lib/python2.7/site-packages/blivet/__init__.py", line 310, in doIt self.devicetree.processActions() File "/usr/lib/python2.7/site-packages/blivet/__init__.py", line 169, in turnOnFilesystems storage.doIt() File "/usr/lib/python2.7/site-packages/pyanaconda/install.py", line 142, in doInstall turnOnFilesystems(storage, mountOnly=flags.flags.dirInstall) File "/usr/lib/python2.7/threading.py", line 764, in run self.__target(*self.__args, **self.__kwargs) File "/usr/lib/python2.7/site-packages/pyanaconda/threads.py", line 168, in run threading.Thread.run(self, *args, **kwargs) DeviceError: ('Cannot destroy non-leaf device', 'fedora_dhcp-29-193-root') Additional info: cmdline: /usr/bin/python /sbin/anaconda cmdline_file: inst.stage2=http://download.eng.brq.redhat.com/pub/fedora/fedora-alt/stage/20-Beta-RC5/Fedora/i386/os/ inst.repo=http://download.eng.brq.redhat.com/pub/fedora/linux/development/20/i386/os/ initrd=F20/Beta-RC5/i386/initrd.img BOOT_IMAGE=F20/Beta-RC5/i386/vmlinuz executable: /sbin/anaconda hashmarkername: anaconda kernel: 3.11.6-301.fc20.i686 product: Fedora release: Cannot get release name. type: anaconda version: 20-Beta Potential duplicate: bug 995892 --- Additional comment from Kamil Páral on 2013-11-07 04:37:59 EST --- Correction: The / partition was marked as reformat, *encrypted* and also enlarge from 50 to 60 GB (I had free space because I deleted /home). --- Additional comment from Kamil Páral on 2013-11-07 08:27:39 EST --- A simpler reproducer: 1. Install a default Fedora LVM install - /boot as standard partition, swap and / as LVM. 2. Reboot into installer again. 3. Go into custom part and reuse /boot and swap. 4. Click on /, click Reformat, click Encrypt and also resize it (I used 6 GB instead of original 8 GB). Click Apply. 5. See that the size was _not_ updated (that's probably related to bug 1027714). 6. Continue with install. See crash during installation start. I believe the root cause of this bug is exactly the same as in bug 1026466 comment 9. It's caused by the resize attempt. The size is not updated in Anaconda GUI, but it tries to perform the operation (probably with some invalid arguments) and it fails.
Bug bug 1076055 created for the problem with resizing the LVM / partition. Fix of 'Device Error' verified on: RHEL-7.0-20140312.0 anaconda-19.31.65-1.el7
