I'm trying to do a new install of 12.04 server on one node of a Dell PowerEdge C6145 with the following spec:
48 cores 512GB RAM LSI MegaRAID 9265 controller 4x2TB disks, configured with RAID5 giving 6TB in total American Megatrends v02.69 BIOS
Booting from a USB with Ubuntu Server 12.04.2 LTS "Precise Pangolin" - Release amd64 (20130214) Expert Mode is turned on (using F6) and doing a clean install of ubuntu server
Its a standard installation except for a manual parition of the disks. I created a new empty gpt partition table on the disk, and added three partitions:
#1 10MB, beginning of disk, /boot, Reserved BIOS boot area #2 512GB, end of dist, /swap, swap area #3 max, /, Mount point: /, Mount options: defaults, label: data Summary: SCSI6 (2,0,0) (sda) - 6.0 TB LSI MR9265-8i 1.0 MB FREE SPACE #1 9.4 MB f biosgrub /boot #3 5.5 TB f ext4 / / #2 512.0 GB f swap /swap swap 1.0 MB FREE SPACE
I selected linux-generic-lts-quantal as the kernel to install, and "generic: include all available drivers" when asked to select drivers to include in initrd.
For additional software:
Restricted software: No Software from universe component: Yes Softare from multiverse component: No Backported software: Yes
When installing the GRUB boot loader, selected Yes to install it to the master boot record. No errors produced and installer skipped over the next item in the main menu "Continue without boot loader"
At "Finish the installation", standard message saying Installation complete and going to reboot
On reboot, get:
error: out of disk. grub rescue>
(hd0) (hd0, gpt3) (hd0,gpt2) (hd0,gpt1)
typing ls (hd0,gpt3)
error: bad filename.
typing ls (hd0,gpt2)
error: unknown filesystem.
typing ls (hd0,gpt1)
error: unknown filesystem.
Rebooting from ubuntu USB and selecting Rescue a broken system: went through various steps until Enter rescue mode reached
/dev/sda3 selected as device to use as root file system Selected Execute a shell in /dev/sda3
$df -l Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 5316685816 901368 5047839028 1% / devtmpfs 264147596 0 264147596 0% /dev /dev/sdb1 5316685816 901368 5047839028 1% /media/cdrom devpts 264147596 0 264147596 0% /dev/pts none 52837212 212 52837000 1% /run
ls /boot shows initrd.img-3.5.0-23-generic and vmlinuz-3.5.0-23-generic and populated grub directory, including grub.cfg. Also /etc/default/grub looks reasonable
Back in the installer, selected "Reinstall GRUB boot loader" Selected /dev/sda and no error or message produced
Rebooting the system again, and I still get the same "error: out of disk" grub error
Booting from the USB again and selecting "Rescue a broken system". Went through the various steps until "Enter rescue mode" reached. Selected "Execute a shell in /dev/sda3"
Ran 'grub-install /dev/sda' and got the message:
Installation finished. No error reported
Ran 'update-grub' and got:
Generating grub.cfg... Found linux image: /boot/vmlinuz-3.5.0-23-generic Found initrd image: /boot/initrd.img-3.5.0-23-generic Found memtest86+ image: /boot/memtest86+.bin done
Rebooting still gives the same "error: out of disk" grub error.
Apologies for the length of this. Any help would be very much appreciated
Some additional details from the grub rescue> prompt. Typing set gives:
Typing ls / or ls (hd0,gpt3)/ gives:
./ ../ lost+found/ etc/ media/ initrd.img var/ lib/ usr/ proc/ dev/ run/ root/ tmp/ home/ mnt/ sbin/ bin/ lib64/ selinux/ sys/ srv/ opt/ umlinuz
There is no /boot directory. Typing ls (hd0,gpt3)/root/ gives:
./ ../ .profile .bashrc
But typing ls (hd0,gpt3)/etc/ gives
error: out of disk.
There are similar mixed results with other directories.
