Date: Sat, 30 Apr 2011 21:42:39 +0100 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII To: linux-btrfs@vger.kernel.org Return-path: List-ID: After completing an installation of Ubuntu 11.04 with a separate /boot partition and BTRFS as the main filesystem (Ubuntu creates subvolumes for / and /home). sda1 being the GPT stuff sda2 being most of the disk as BTRFS sda3 being /boot sda4 being swap sdb having an identical partition table... I patched everything up to date, rebooted to make sure that all was ok.. and then ran:- btrfs device add /dev/sdb2 / sync reboot The system stops in initrd unable to find the root filesystem... It's my understanding that nothing should change here, am I missing something, I don't see how it can even tell I've added more storage, let alone fail to boot. -- A.
