<pre wrap="">It appears that the latest dracut release "006" has implemented an attempted fix.

However, when I install dracut 006-2 before installing the final kernel
and rebooting, I still get the same error.
I found this which gives instructions on how to do it with F13 beta:

And only now is it able to boot with a btrfs mirrored /
I think I had to reinstall the OS 9x to get this right --- by far the most painful install I have ever done.
Below are the instructions in case the link is deleted. The instructions are missing the "btrfs-vol -b / " step. That step will hang on the 2.6.33 kernel from fedora 13, but it recovers when running again after a reboot and re-running under 2.6.35 (built from an SRPM from koji).
My Bugzilla request has yet to be answered and #dracut on Freenode was unresponsive to help requests 4x.

<h1 class="title">Btrfs root with Multiple Devices in Fedora 13 (beta)</h1>
<div class="post-content clearfix">
<p>install via:<br>
<code><br>
linux btrfs<br>
</code><br>
update first<br>
<code><br>
yum update<br>
</code><br>
edit /etc/dracut.conf:<br>
<code><br>
add_dracutmodules="btrfs"<br>
</code><br>
edit /usr/share/dracut/modules.d/90btrfs/install:<br>
<code><br>
dracut_install btrfs<br>
inst_hook mount 90 "$moddir/scan-btrfs.sh"<br>
</code><br>
create /usr/share/dracut/modules.d/90btrfs/scan-btrfs.sh:<br>
<code><br>
#!/bin/sh<br>
if [ -n "$root" -a -z "${root%%block:*}" ]; then<br>
modprobe btrfs<br>
btrfs device scan<br>
fi<br>
</code><br>
re-generate initramfs:<br>
<code><br>
dracut -f<br>
</code><br>
Now you can add more devices to root<br>
<code><br>
btrfs-vol -a /dev/sdd /<br>
btrfs-vol -a /dev/sde /<br>
</code><br>
Reboot! You can make it!</p>

This works fine until I try to build a RAID1 mirror because the kernel
must be notified of all devices as a scan doesn't happen automagically.
So I see there is somehow a way to do this with dracut/initramfs, but
I'm lost on that.
Anyone have any ideas?
