Bug#574817: libata transition breaks mdadm arrays

[Mathieu Parent (Debian)]

Hi,

It is now working! I don't know what changed since last failure (no
package upgrade as ftp-master.d.o is borken).

Summary:
- Upgrade from linux 2.6.32-9 to 2.6.32-10 (the libata transition big
bang release), then reboot
- Only 2 disks of the 4-disk array are assembled

Summary of all the changes made:
- upgrade to mdadm 3.1.1-1+incremental+4
- enable INCREMENTAL by running dpkg-reconfigure mdadm (or by editing
/etc/defaut/mdadm)
- /usr/share/mdadm/mkconf > /etc/mdadm/mdadm.conf (with backup)
- update-initramfs -u -k all
- reboot, reboot, reboot (many times)

Thanks Martin!

I think we should wait some days before marking this bug as fixed.
Also, as default is not incremental, we can keep it open for
information.

Cheers

Mathieu Parent
