However, as it's month-end, it takes longer than usual to get an ISO published. Once it's published, we'll also be publishing a README on how to prepare the network sources to support a btrfs-based root filesystem.
However I still don't see how to do this. Just as with the full DVD install there isn't an option to use btrfs when laying out the fileystem in the installer. Anyone know how to do this?

The ISO now creates a btrfs snapshot on install, which is more aligned with best practices when using btrfs for a root filesystem. Obviously, you can install as normal and convert to btrfs, but that is way more tedious than installing onto btrfs from the start. I apologise for the inconvenience, and not editing the release notes. However, given that we're hopefully only a few days away from having the new ISO published and how long it takes to update release notes, I may just leave them in place for now. :)
Dude - I think you're missing our point. It was stated in the release notes it could be done upon install, create btrfs root filesystem, when 6.3 was released. We now know, this was not the case, the supplemental ISO is lagging behind - that's fine, it's just the documentation was wrong. I will follow your guide above; thank you for posting that.
Dude wrote:You don't want to convert with the normal RHCK install DVD: the version of btrfs in the Red Hat kernel is woefully old, which is why we don't use it and why we didn't modify anaconda to allow you to create btrfs root filesystems with it. Please wait until the UEK2-based boot ISO is released, both for normal installs and conversions.
My point is that I see no point to bother setting up a network install just for the purpose to setup a root btrfs filesystem. That's why I posted instructions how to convert the existing root partition using the boot.iso image. But, whatever suits....
Dude wrote:Yes, you can use the current Fedora Live CD without a problem. That's what I did during my demos and until the UEK2-based boot ISO was created.
Ok, I see. Old btrfs version with the existing boot.iso... That's certainly a point. I was actually assuming it was uek2, but did not check. Would it be ok to use the latest Fedora Live CD?
Anyway, I still wonder why it is more tedious to convert the existing root partition. Think I'd still rather convert the file system using the new boot.iso with UEK2 kernel, when it is released, rather than setting up a network install. Ok, LVM is another thing. Is there a network install available with a ULN subscription?You can do a network install without any subscription: ULN is not a network install source. Just copy the contents of the OL6U3 DVD to somewhere on your network that is accessible via HTTP or NFS. Boom, you're done. For the UEK2-based boot ISO, you then need to replace the install images in that source with the new ones from the Boot ISO. We will be releasing a README/how-to with the ISO when it's released.
Dude wrote:Yes, we've been talking about having network-based install sources on public-yum.oracle.com, but haven't made a decision yet. Keep in mind that corporate installs would usually use local install sources over anything on the Internet, as they would already have servers for patching and provisioning. Most corporates already use network-based installs using PXE anyway. It's far more likely that this would be used by small companies rather than large ones.
I think it would be great if Oracle Public yum or another service could also provide a Oracle Linux network install. Perhaps it won't necessarily mean more bandwidth considering that people do not need to download the entire distribution images anymore. Setting up another http or file server may be restricted in some corporate vLAN's.
