Who has had success with 3TB GFH? [Solved] (2 replies)

I have solved my problems below. The short answer is that I was not using an appropriate kernel. I updated and now all is well. My setup is described below:

my uboot:
http://download.doozan.com/uboot/files/uboot/uboot.mtd0.goflexhome.davygravy-2012-04-19.kwb

my kernel:
Linux-3.3.2-kirkwide from the rescue image

my partitions:

Recovery/transformation command (? for help): p

Logical sector size: 512 bytes
Disk identifier (GUID): E6D0FDC0-0A69-47A9-B3DF-672B315FAB76

my filesystems:

ext4 for /dev/sda2 (media storage)

I am having some trouble with my 3TB GFH.

I would like to know who has had full success with the 3TB GFH. By full success I mean:

• Successfuly boot linux from the drive
• Have access to the entirety of the drive (bonus if this is nearly all in 1 partition)
• No significant compromises (net/usb booting, awkward partition setup with symlinks, etc)

I am particularly interested in a few aspects of the setup.

1. The partitioning scheme
2. Software versions (kernel and uboot, and setup if non-standard)
3. The filesystem choice (ext2/3/4 or other)

I have been trying to do my setup with a hybrid MBR using the latest "official" (April 2012) release of uboot from Jeff and Davy. I have yet to get it to boot. I have found that information on a good hybrid MBR setup is very scattered, with people saying that they were successful, but not giving the details. (At least not clearly enough for my feeble mind)

I notice that a lot of people separate their boot and root partitions, is there a need for this for using the Hybrid MBR or is this just their personal partitioning choice? and what about the following question?
"Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N)"

I ultimately want to have 2 partitions: one for the system, and one for data to be served up on the network.

I have tried the following setups (all partitions formatted ext4): (hybrid MBRs were setup according to my understanding of rodsbooks - Creating a Hybrid MBR)

1
GPT: boot and root in one partition,data storage in another
Hybrid MBR: Boot/Root Partition

2
GPT: boot and root in one partition,data storage in another
Hybrid MBR: both partitions

3
GPT: boot and root in one partition,data storage in another
Hybrid MBR: no hybrid

4
GPT: boot and root in one partition, no other partitions
Hybrid MBR: boot/root partition

5
Normal MBR: boot and root in one partition, no other partitions

I have not had any success with any of these.

I believe that the uboot environment that I have setup is pretty standard. I try to boot USB, then SATA, then rescue and have no problem booting the other two.

Is ext4 the problem?
