Linux Ext4 is the latest in a long line of Linux file systems, and it's likely to be as important and popular as its predecessors. As a Linux system administrator, you should be aware of the advantages, disadvantages, and basic steps for migrating to ext4. This article explains when to adopt ext4, how to adapt traditional file system maintenance tool usage to ext4, and how to get the most out of the file system.

Backwards compatibility?

ext3 added a lot in exchange for nothing as partitions could still be read as regular ext2 from other operating systems such as Windows or BSD. This is important because ext3 and 4 features are very expensive if you just want to grab a few files as opposed to running off it.

With ext4 you lose all the backwards compatibility for very little.

"for very little"? what the hell have you been smoking - what do you define as very little?

Good lord, what is it with these negative ext4 bashers coming out of the woodworks?

I thought ext4 gave you a big performance boost for free. I think it's nice that you can choose more performance or keep compatibility with old systems.
