I attempted to install 11.04 on a Dell PowerEdge-R610 that has a LSI SAS1068E-based hardware RAID setup (I think). Installer finishes without a hitch, but upon reboot, it appears that Grub can't find the boot partition and drops to the busybox shell.
Here is the partition table on the RAID device.
Disk /dev/sda: 72.7 GB, 72746008576 bytes 255 heads, 63 sectors/track, 8844 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d08d6 Device Boot Start End Blocks Id System /dev/sda1 * 1 6757 54272000 83 Linux /dev/sda2 6757 8845 16765953 5 Extended /dev/sda5 6757 8845 16765952 82 Linux swap / Solaris
And here is the Grub script as produced by the installer. The msdos stuff looks fishy to me. (Please note, this was typed by hand and may contain typos.)
setparams 'Ubuntu, with Linux 2.6.38-8-generic' recordfail set gfxpayload=$linux_gfx_mode insmod part_msdos insmod ext2 set root='(/dev/sda,msdos1)' search --no-floppy --fs-uuid --set=root 22f9995f-8060-4893-9b9a-bed1d2635384 linux /boot/vmlinux-2.6.38-8-generic root=UUID=22f9995f-8060-4893-9b9a-bed1d2635384 ro quiet splash vt.handoff=7 initrd /boot/initrd.img-2.6.38-8-generic
Any thoughts on how to get this working?
