You can mount ext2 as ext4 filesytem (just read...)

So - this is tough to even explain.  Imagine all of your build scripts and SOP simply read # mkfs /dev/VolumeGroup/Volume and then you add the following entry to /etc/fstab /dev/VolumeGroup/Volume /directory ext4 defaults 1 2 then when you run # mount -a Everything is cool.  Except .. it's not. That mkfs command created an ext2 filesystem - the crappy part is when mount command is run, even though fstab is expecting ext4, it doesn't care and mounts it anyhow.  So, now we have a filesystem with no Journal and added ext4 features. Worse yet - there is no "supported" upgrade path to ext4.  However, you can add a Journal to make it ext3. # tune2fs -j /dev/VolumeGroup/Volume
