How are you using a 3.2 Debian kernel on a coreos image?

@gregkh he is using a Debian system to run the coreos-install script I presume.

I'm using a debian 7.5 Dom0 with xen. I'm trying to install coreos into a DomU in a lvm lv, using the coreos-install script using the LV as a device.

@lordfolken use the CoreOS ISO to run the coreos-install script.

or if you want to install in Dom0 write the coreos disk image to the right lv volume but pass the cloud config in via a different method such as config drive. then you never have to mount the btrfs volume or deal with the disk image's partition table which is also an issue when using lvm.

Regarding btrfs compatibility issue, I may disable the incompatible features if they don't gain us anything but I haven't looked into it yet.

@c4milo How do you use ISO with (or "provide ISO to") coreos-install script? I cannot find any documentation about this.

So what are required BTRFS features (thus minimal kernel version) to run coreos-install script?

@c4milo Which refers to "Installing CoreOS to Disk":

The most common use-case for this ISO is to install CoreOS to disk. You can find those instructions here.

Itself not giving any clue on ISO use-case.

@C-Duv the process is as follow:

  1. You download the CoreOS ISO image
  2. You boot it up in your machine
  3. Once it gives you a prompt, run can run coreos-install -d /dev/sda -C beta

I thought that was clear in the documentation.

Oh, that way (use recent and compatible system to perform installation)! Finally, it's what I did and it worked :+1:
