I had experienced something similar in 11.04 when attempting to install grub on a RAID 1 /boot partition. My resolution was to partition like this:
sda 1GB sda1 - '/boot' ext2 | 100GB sda2(md0 - ext4) '/' | max sda3(md1 - ext4) '/array1' sdb 1GB sdb1 - not mounted, ext2 | 100GB sdb2(md0 - ext4) '/' | max sdb3(md1 - ext4) '/array1' To the best of my knowledge, this is a problem with GRUB2(I'm pretty sure there are existing bugs filed for this). The unfortunate side effect of this is that /boot is not redundant, but it only takes a few minutes to reinstall grub on another free partition, like sdb1 if sda fails. I wound up leaving a spare 1GB partition at the beginning of every disk in that machine for that reason. I'll be trying something similar on a new box with Ubuntu 11.10 in the next few days, I'll post back my results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/881465 Title: ubuntu 11.10 crash at the end of installation with mdadm raid setup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/881465/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
