By changing grub-mkconfig, update-grub no longer fails and I can produce a valid grub.cfg. However, grub still fails at boot with "Unknown Filesystem" in up-to-date ubuntu karmic and leaves you at the rescue prompt.
However, I can boot to a root btrfs filesystem. My setup: /dev/sda1 is /boot (ext2) /dev/sda2 is / (btrfs) Rebuild your initrd after adding btrfs, libcrc32c, crc32c, and zlib_deflate /etc/initramfs-tools/modules. The grub rescue commands go something like this: set prefix=(hd0,1)/grub insmod linux linux (hd0,1)/vmlinuz-2.6.... rootfstype=btrfs root=/dev/sda2 ro initrd (hd0,1)/initrd-2.6.... Since I don't boot so often, I'm happy to have this working. -- grub-probe fails with btrfs root (and ext3 /boot) https://bugs.launchpad.net/bugs/450260 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
