Could you explain step by step how to install debian-jessie on Gen2?
I also think of changing my gen2 system from WD firmware ver.2 to Clean Debain system.
I know how to install debian-jessie with clean partitions.
But, I don’t know how to install clean debian-jessie with preserving the data partition.
It would be nice if I can install clean debian-jessie from ssh on WD firmware ver 2, if possible.
But, if it is not possible, it doesn’t matter.
Thank you in advance.
This is basically same as guide provided by Fox_exe, I am posting same here with changes. When using parted you can run “print” or “p” before making any changes to check your partition table.
I have “NOTE” before every line that I have modified.
[code]======= INFO ===========
/dev/sda1 - Swap
/dev/sda2 - User data
/dev/sda3 - Rootfs/Boot (Important for bootloader)
======= FW SETUP =======
Copy uImage, uRamdisk and rootfs-jessie.tar.xz to /boot/boot (Overwrite all)
Reboot
Connect via telnet
Repart HDD (Skip 3rd partition):
parted /dev/sda
####NOTE###
DON’T do “rm 2” as /dev/sda2 is our data partition, use print to check current partition table##
rm 1
#[dont run] rm 2
rm 4
rm 5
rm 6
rm 7
mkpart primary 0% 1G
q
mkfs.ext4 /dev/sda1
Move firmware to data partition (temp)
mkdir -p /mnt/root /mnt/data
mount /dev/sda1 /mnt/data
mount /dev/sda3 /mnt/root
cp /mnt/root/boot/uImage /mnt/data/
cp /mnt/root/boot/uRamdisk /mnt/data/
cp /mnt/root/boot/rootfs-jessie.tar.xz /mnt/data/
umount /mnt/root
End format HDD…
parted /dev/sda
rm 3
###NOTE###
don’t run this line, as it is meant to create new data partition /dev/sda2
[don’t run]mkpart primary 4G 100%
###NOTE###
we need to modify below line as there is space in the disk before start of /dev/sda2, we can have larger /dev/sda3
##[DONT RUN}mkpart primary 1G 4G
Instead run “print” to check the start point of /dev/sda2 which shall be 8591, so we can create /dev/sda3 as below
mkpart primary 1G 8.5G
q
###NOTE###
Don’t create filesystem on /dev/sda2
##[DONT RUN}mkfs.ext4 /dev/sda2
mkfs.ext4 /dev/sda3
Prepare new firmware:
mount /dev/sda3 /mnt/root
tar xvf /mnt/data/rootfs-jessie.tar.xz -C /mnt/root
mkdir -p /mnt/root/boot
cp /mnt/data/uImage /mnt/root/boot/uImage
cp /mnt/data/uRamdisk /mnt/root/boot/uRamdisk
umount /mnt/root
Convert 1st partition to Swap:
umount /mnt/data
mkswap /dev/sda1
Reboot. Done!
sync
reboot -f
======= OMV SETUP =======
Connect to device via SSH
Default SSH login/password: root/mycloud
Install latest OMV (v.3.x.x, “erasmus”)
echo “deb Index of /public erasmus main” > /etc/apt/sources.list.d/omv.list
echo “127.0.1.1 wdmc.lan wdmc” >> /etc/hosts
apt-get update
apt-get install --force-yes openmediavault-keyring
apt-get update
apt-get install openmediavault
choose “none”, “yes”, “standalone”
Default OMV login/pass is: admin / openmediavault
Warning: create network interface in webgui or you loose network connection after restart!
“Mount” data partition (/dev/sda2) as “User data”.
Configure all other things.
Profit!
to allow USB to work update to this kernel
just unpack to rootfs and reboot

Thank you very much. It’s more than I expected.

I am on a Gen2 6TB but it looks like partition 4 is the data partition with the size of 6GB.
4 4828MB 6001GB 5996GB ext4 primary
Did i miss something?
Data partition should be close to 6TB in size not 6GB. Can you post output df -h, through ssh. or fdisk /dev/sda followed by print
EDIT: on second look it is 5996GB not 6GB, in that case it is data partition. Still you can confirm by running above commands. You can also try mount | grep /dev/sda
Are you sure it is GEN2 mycloud and not GEN1 or mycloud EX* or something else?
of course 6TB, confused it 
already messed it up, could not delete some partitions because they was mounted. Guess the my cloud will not work after a reboot. At the moment i can log in over the web interface and see my data

Have you missed this step before deleting partitions ?? If so you can still do this while you have access over ssh or telnet.
Yes, looks like data is on /dev/sda4, /dev/sda3 is swap, that means you probably have deleted root partition. I think you still can recover by creating proper partitions and installing debian on that. Do not delete /dev/sda4
Have copied them and rebooted. done it with WinSCP
Any Idea how to solve this?
(parted) rm 1
Error: Partition(s) 1, 2 on /dev/sda have been written, but we have been unable
to inform the kernel of the change, probably because it/they are in use. As a
result, the old partition(s) will remain in use. You should reboot now before
making further changes.
WDMyCloud:/mnt# mkfs.ext4 /dev/sda1
mke2fs 1.42.5 (29-Jul-2012)
/dev/sda1 is apparently in use by the system; will not make a filesystem here!
I have no experience with winscp, can’t help with it.
I have no /boot/boot the files are in the directory /boot. Do i have another device or need a special Firmware to start from?

AFAIK , your device has different partition scheme. I have no 15 MB partition, like your /dev/sda1. It appears that /dev/sda1 is your ESP partition for GPT (secure boot). I am not sure how to proceed here. You can try creating two new partitions One for swap and another for /root, as in above guide and unpack jessie-rootfs.tar.gz (it is not .xz as in above guide), there and uImage and uRamdisk to /root/boot/ before reboot.
EDIT: At the end try to have only 3 partitions, one with your data /dev/sda4, another one for swap (empty) and one for root, having unpacked jessie-rootfs on / and uimage and uramdisk on /boot/.
You shall also check /etc/fstab to confirm with your current partitioning before reboot, as may be designed by Fox_exe with some other partition scheme in mind.

There is init script provided with debian.
Though better options is to use ntp.
apt-get install ntp
ntpq -p
if required
dpkg-reconfigure ntpThanks docbroke. I used the wrong files. Have a Gen1 and not 2. Recovery was not possible for me, could not write the imsages. Have the system set up anew.
Install of Debian works now but i cant get the openmediavault to install. Any idea what i did wrong?
Hmm change this line:
echo “deb Index of /public erasmus main” > /etc/apt/sources.list.d/openmediavault.list
to
echo “deb Index of /public stoneburner main” > /etc/apt/sources.list.d/openmediavault.list
Now i can install it.
Got another error with collectd

How did you install debian? Something is wrong with your debian installation, it is not willing to install any dependencies of openmediavault.
No luck after restart the Device hangs with green LED and ist only reachable with ping. No Web GUI nor telnet reachable
When i use Clean debian - english.7z for OMV Install latests OMV in Wheezy.txt it should be working?
Do i need the config.img in the OpenMediaVault directory?
You may try one more reboot.
Is there a compiled samba 4 bin for 4k debian? I’ve installed a clean debian and updated it to the latest possible version, installed samba v4 but the speed is depressing. I’m getting something around 20MB\s with any settings i try.
Strange. Minimum is 45/30 (Read/Write) MB/s (W/o any tuning).
Up to 75/40MB/s after tuning and ~90mb/s after replace samba to WD version.
Google for “Tuning samba for RaspberyPI”. We have similar hardware, so almost all instructions can work.

Just reinstalled a clean system and updated it.
PRETTY_NAME=“Debian GNU/Linux 9 (stretch)”
NAME=“Debian GNU/Linux”
VERSION_ID=“9”
VERSION=“9 (stretch)”
Samba version 4.5.8-Debian
Nothing like custom bins and config is default (only 2 shares added). Maximium writing speed i get is 25 MB\s.
I’ve managed to get 130 MB\s using a piece of software named TeraCopy but it drops back to 25 MB\s after writing 1,4GB or so. I’m not even sure if it’s real or a bug (IOTOP never shows DISK WRITE greater than 35 MB\s).
Can you please give me the contents of your smb.conf? Also is there a custom bin i can install for my system?
I’ve tried pretty much any combo of socket options and cache settings from this topic but never got anything better than 25 MB\s.
