Message-ID: <baab8ccb0905201624j56767f59mff537ab8767ffc8d@mail.gmail.com> Date: Wed, 20 May 2009 19:24:02 -0400 From: Matt LaPlante <cybrmatt@...il.com> To: linux-ext4@...r.kernel.org Subject: Mounting Ext3 with Ext4 According to the Ext4 howto (http://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4), "It is possible to mount both ext3 (and ext2, in kernels 2.6.28 and later) filesystems directly using the ext4 filesystem driver." So this means, if I'm reading it correctly, that a kernel built with ext4 support should be able to mount and manage ext[234] filesystems. Is that correct? If so, are there any limitations on this support? I'm running Ubuntu Jaunty with some custom-built 2.6.29.4 kernels and grub2. I seem to have no problem booting from ext4 disks, so the ext4 support is definitely there and functioning. I had hoped the ext3 support meant I could build the kernel with ext4 only and carry on as usual with my ext3 partitions. Unfortunately doing so causes the ext3 partitions to fail to boot. So... booting ext3 with ext3 in the kernel=fine booting ext4 with ext4 in the kernel=fine booting ext3 with ext4 (only) in the kernel=not fine Is this a problem or was it never intended to work? - M@ -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
