We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply
