Okay, this is sort of off-topic, but nevertheless interesting... ;-)

The /vanilla/ Linux kernel tree has now entered "release candidate 2"-stage,
and some very "new" things - in the sense that the Linux kernel did not
support them before - have been added to the kernel tree on the filesystem

The first release candidate already featured RedHat's /GFS2/ distributed
filesystem - see...


.... for more information on /GFS's/ ancestry - /GFS2/ is not covered by the
article, I'm afraid - but as of /linux-2.6.19-rc2,/ a new "Linux native"
filesystem has been added for server storage, namely /ext4./ It is very
similar to /ext2/ and /ext3/ for most part, but the revolutionary thing
about it is that it's spread out over two different (but somehow linked)
partitions, which should ideally be placed on separate hard disks. In this
(and in its intent), it's somewhat similar to a RAID-0 configuration.

The basic principle is that one partition will be used to store the
directories, while the other partition will be used to store the files.

You can read more about it here, and as you will be able to ascertain from
the document, /ext4/ has already been in development since 1997 and kernel
2.1... ;-)
