btrfs multi-device fs causes boot fail with "mount: wrong fs type, bad option . ."
Last modified: 2011-07-19 14:57:11 EDT
Description of problem:
initramfs is still not properly running btrfsctl -a <device> to import devices so that a btrfs mirror / can be mounted
Version-Release number of selected component (if applicable):
latest & greatest. -5 I think?
Is this redundant of the next question?
Steps to Reproduce:
1. Install Fedora 13 with btrfs fs on /dev/sda2 as /
2. Build & install kernel-2.6.35-0.35.rc4.git5 from SRPM from koji.
4. run: btrfs-vol -a /dev/sdb2 /
btrfs-vol -b /
5. Wait for finish.
6. Build & install kernel-2.6.35-0.36.rc4.git5 from koji to get new initrmfs.
mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try dmesg | tail or so
Can't mount root filesystem
Boot has failed, sleeping forever.

I resisted the urge to mark this bug "Urgent" though it is from my perspective.
Can anyone please help me fix this from a rescue CD? I can get the /boot and / to mount again, but making a new initramfs is beyond me. I will seriously order you a reasonably priced pizza.
Even after building dracut-006-02 and installing before the last reboot, I get the same result.
contains instructions on a mod that gets this to work. I haven't tried with dracut-005-3, but only with 006-2 which I built from the SRPM from koji for f14.
Also the btrfs-vol -b / step hangs on the 2.6.33 kernels that I tried. I'd recommend going to the latest you can download and build from koji.

I apologize for not testing your updates. After updating my system from F13 to F15, this problem came back. Going back to the "happy penguins" link above, I was able to uninstall and reinstall the 2.6.38 kernel RPM. Can anyone else confirm this? Have I actually created the problem on my own system that's incompatible with dracut?
