Hello,
Is it possible to a new-clean install oracle linux 6.4 onto btrfs partitions/filesystem ,Any documentation on this, if so how is this done ?
Using dvd install ->http://ftp.linux.org.uk/pub/distributions/enterprise/OL6/U4/x86_64/OracleLinux-R6-U4-Server-x86_64-dvd.iso
Thanks Glenn

    Here's the documentation for installing BTRFS root file system using OL 6.3. This should work for OL 6.4 too, just use the OL 6.4 UEK boot ISO and OL 6.4 ISO:

    http://docs.oracle.com/cd/E37670_01/E37355/html/ol_installroot_btrfs.html

    Let us know how it goes.

    Hello,

    The normal boot.iso and the iso for 6.3 and 6.4 doesn't include the needed to boot and create a btrfs filesystem from the the installer, however it does have the capability to use one that already exits.

    There is a 2nd modified UEK boot.iso that allow install on btrfs.

    So you have 3 options., not sorted from difficult to easy, so please check what will work better for you

    1. Boot with any other Linux dvd that can create btrfs filesystem, say ubuntu or any other one, and create the filesystem layout and format. Then boot innto 6.3 or 6.4 and you will be able to use that btrfs filesystem as root.
    I do recommend something like /boot, / and swap

    2. go to e-delivery.oracle.com/linux and download a special boot.iso that include the bits to boot and create a btrs using the installer (anaconda)

    If you haven't used e-deliver, you can check a blog post I did about that

    http://kikitux.net/ol/getting-started-with-oracle-linux.html

    Part 3 describe the several isos for 6.3 but the same apply to 6.4

    3. go to my blog, and I have links to same shares on dropbox, if not working the download today, retry tomorrow as they suspend my public download after 20GB quota per day

    http://kikitux.net/dropbox

    I have a modified ISO for full DVD and a template for virtualbox that already is with / as btrfs..

    good luck.

    Alvaro

    Yes, it does. The UEK boot ISO was specifically created for OL6 to install directly onto a btrfs filesystem. The README associated with the UEK boot ISO also explains exactly how to do this.

    I did rewrite my post, I was referring to the boot.iso that came inside the full dvd and the normal boot.iso.

    Yes, there is a btrfs boot.iso with a Readme that have the instructions.

    Hello,

    I will use btrfs on this install set. I hope this install image has it included.

    Oracle Linux Release 6 Update 4 UEK Boot ISO image for x86_64 (64 bit)      V37090-01      196M

    Thanks for the info
    Cheers Glenn


    From readme link:

    Installing Oracle Linux using the Unbreakable Enterprise Kernel
    ---------------------------------------------------------------

    For compatibility reasons, the default installation image of Oracle Linux boots
    the Red Hat compatible kernel to perform the installation.

    Oracle provides an alternative installation image that supports the
    installation of Oracle Linux 6.4 using the Unbreakable Enterprise Kernel (UEK)
    as the installation kernel. This installation method also supports creating a
    root file system using the Btrfs file system.

    This ISO image does only contain the bootable installation image, it requires
    a network installation source that provides the actual RPM packages.
