According to the ext4 howto, once extents are enabled, the filesystem can not be mounted by ext2/3 tools: âIf you convert your root filesystem ("/") to ext4, and you use the GRUB boot loader, you will need to install a version of GRUB which understands ext4. Your system may boot OK the first time, but when your kernel is upgraded, it will become unbootable.â So I guess for now we at least need to document that ext4 is not supported. The long-term plan could probably be to PV-ize grub2 of course...
