Description of problem: Configuring custom partitioning on an existing F18 system with / on an lvmlv gets the error: /boot filesystem cannot be of type lvmlv Version-Release number of selected component (if applicable): anaconda-20.25.15-1.fc20 How reproducible: Always Steps to Reproduce: 1. Partition a system with / on an lvm and no separate /boot 2. Start on installation of Fedora 20 3. Select custom partitioning and use existing partitions Actual results: The installer reports: Error checking storage configuration On expansion it shows the error: /boot filesystem cannot be of type lvmlv Expected results: The installation should proceed since it's a valid configuration. Additional info: This system was installed with Fedora 18 which did not complain about /boot on lvmlv. I was able to install Fedora 20 using kickstart with the identical configuration which shows the configuration is valid. Thanks -- Ian
We have disabled support for having boot on lvmlv as of Fedora 20 due to the serious issues the tools we use for bootloader setup have with using an lvmlv for boot. I believe Dave Lehman can provide a more detailed answer, so I'm adding him to CC.
/boot on lvm and btrfs have both been disabled due to issues with bootloader tools. What was allowed in the past is irrelevant. Sorry for the inconvenience.
