Bug Description
Binary package hint: base-installer
I am attempting to install Ubuntu Server Edition 10.04 and configure 2 brand-new hard drives (500gb SATA) to use RAID 1.
I have a post at ubuntu forums (http://
I'm following this guide https:/
I've set up 1 physical partition and 6 logical partitions, and the physical partition on both drives is /boot and both are flagged as bootable.
The installer appears to behave correctly (as compared to the guide referenced above) for the most part, although there were times when I would pair two partitions (e.g. sda3 and sdb3) and then when I go on to pair another 2 partitions, sda3 and sdb3 are on the list again! Also some mds would have the phrase "Software RAID" associated with them, while others are "Unknown". It is possible that these strange issues could be related to me doing a reinstall (I've tried doing this 3 times).
After partitioning the hard drives and setting up RAID, the Ubuntu installer proceeds to finish up normally (installing the base system, configuring APT, etc), and when I reboot, GRUB2 fails to load and I get an error message saying that one hard drive is degraded. I boot into the initramfs shell, and when I do cat /proc/mdstat, I get this output:
