    Exclamation Where is the option for EXT4?

    Just doing a clean install of 9.04 dual booting with vista, I cant seem to find the option for Ext4.

    Anybody know?

    Would this have anything to do with dual booting with vista?

    Should be in custom partitioning---you can also change ext3 to ext4 after your install---look thru the closed Jaunty testing forum.

    when you install you have the opportunity to set file system to ext4

    you should be able so state using mkfs command
    You do what? Are you crazy!

    I use Ubuntu Remix, but I have not found the option during partitioning to use ext4.

    Have I just excitingly overlooked it or is it not available for Remix version?
    Can I still convert it?

    bye

    As I said above--look in the closed Jaunty testing forum---there are detailed instructions to convert a ext3 install to ext4---

    You need to be using a LiveCD or from another install on your system--The other thing that you need to remember is that you MUST be using Grub from Jaunty--if you updated your install, the grub from Intrepid or older WILL NOT BOOT from ext4--

    You will need to uninstall the older grub COMPLETELY & then install the newer grub that comes with Jaunty...I can not stress this enough---if you use the older grub your system will be UNBOOTABLE as soon as you convert to ext4.

    I'll look thru the closed forum for some links--I'll post them shortly. Generally, ext4 is about 10~50% faster--You will see a large difference with large file transfers--a very small difference with lots of little file transfers. My system (1.5TB of drives--4 SATAII units & i7 920 desktop) went from a average of 30MB/s to 50~55MB/s on large transfers--up from 15~18MB/s to 25MB/s on small batch transfers---Your mileage will vary depending on your system.
