GoFlex 3Tb can't make 3Tb partition

[AndrewWArchLinux]

I've got a goflex 3Tb and installed the latest version of goflex including uboot (as far as I know)
using the instructions from
http://archlinuxarm.org/platforms/armv5 ... oflex-home

I found that i could not access a partition greater than 2TB, down to the MBR partitions which do not support large disks, and GPT tables are ntt supported by uboot. Tried with Hybrid ones as described below but no luck


viewtopic.php?f=53&t=7291


I saw the patch recommended in the above post which seemed to fix the issue, but do sure when to install is this from USB (which i have done) or from MBR on the disk?


I take is as in installed yesterday for the 1st time i have the latest uboot as described
viewtopic.php?f=53&t=7290
and presumably patched by the last entry in viewtopic.php?f=53&t=7291, but still i cant get the system to boot


Any ideas think it may be something simple i have missed?

Thanks

Tried a different approach
created a single 20Gb partition MBR
installed archlinux
labeled rootfs
rebooted .
worked......
installed gdisk
changes partitions to hybrid
rebooted
failed.........
booted from usb and found partition was corrupt
did a new mkfs -t ext3 /dev/sda1
relabaled rootfs
installed archlinux
rebooted
failed..... just flashing light on front of nas
its defiantly do do with the partition type

still going round in circles, this ios what I am doing looks to follow off the posts i have found, what ave i missed

U-Boot does support GPT. Don't use hybrid. It was a workaround for older U-Boot versions and there is no reason to use it now. Use GPT, 1 separate partition for rootfs, extract tarball - done.

thanks , but no luck ..... tried what you said

I only installed yesterday so i must have the latest version (if that is what is deployed with the current build scripts) how can i tell?

I just get the green flashing light on the front.

Any ideas ?

Thanks

[AndrewWArchLinux]

For any one else looking for this solution Moonman was right the latest uboot does work well. The only issue is when you follow the instructions the latest version is not installed......... caught me out....

Follow the instruction on the uboot sticky link up upgrade, make sure your disk is GPT only

and it works fine ;)

[hecatae]

may I suggest installing rescue system as your next point of call, you dont want to lose access to your 3tb drive.

Please AndrewWArchLinux, could you tell me what were the steps you did to install archlinux in 3TB GoFlex Home, as I have intentions to install one like yours.

[AndrewWArchLinux]

1. This may fail and brick you device, this is done at your own risk
2. You WILL lose any information stored on the disk, if you want the data back it up somewhere else
3. Create a recovery boot usb stick (look on the forums for instructions). Ensure you also have the OS as an image files on the usb as well VERY VERY IMPORTANT
4. Test the USB boot works (you will need it) VERY VERY IMPORTANT

5. Installed Archlinux as per
http://archlinuxarm.org/platforms/armv5 ... oflex-home
this worked well but only used 2TB of the disk.

6. upgrade U-boot from
U-Boot v2015.10 released
viewtopic.php?f=53&t=8857

The reboot WILL fail with one light flashing on the front of the go flex. Your device is semi bricked at his point.

7. Boot from the USB stick
Prep you disk as per my entries on this link the working partition GPT ONLY NO MBR, and the tunefs , mkfs statements
8. Mount the volume and copy the OS image from the on the USB stick to the goflex and extract

Reboot . done


You will need to have a knowledge of linux to do this as the install instructions are not very good ( in my opinion) as they are out of date, and also the install does not include the latest u-boot, required for the 3Tb disk
so reading the scripts to see what is going on will be a bit help

Guys, yesterday I installed Arch Linux ARM in my GoFlex Home 3TB!

I wrote a guide step by step. The text is in Brazilian Portuguese, but people of other languages may follow commands without too much difficulty.
http://www.luthiano.com/Instalando-Arch ... Flex-Home/

I intend to write a guide to installation and configuration of SAMBA. Any tips?
