just a stupid question, is the this bug related to not writing down the
grub info correctly onto both disks?
It wouldn't start on the first disk either if there would be something
wrong inside initramfs and from what I can see the raid itself seems to
I wrote a hack for BQ back in the day of centos4 because
grub-install/initrd had problems writing down the correct grub info on
some systems where I was running a raid1 for boot and raid5 for the
rest. This hack is included in all BO and seems to work correctly
re-writing the grub on each shutdown/reboot.
I'll make a test later today and see if this is the problem and if it is
then we already have a fix for it.
