HC2 won't show in network

Unread post by vampster » Mon Feb 03, 2020 10:21 pm

Hi,
I have purchased my very first Odroid HC2 and I want to use it as a NAS device. I am following the instructions on https://magazine.odroid.com/article/nex ... droid-hc2/

I have installed ubuntu on a 16GB SD card succesfully (from https://odroid.in/?directory=.%2Fubuntu ... HC1_HC2%2F, file ubuntu-18.04.3-4.14-mate-odroid-xu4-20190929.img.xz ) and could boot the device.
I am connecting to the unit with putty over the network (I do not have the serial interface).
I have updated the OS according the instructions, only the command sudo apt install linux-image-xu3 did not work because the package was not found. Not sure if this is a problem.

Since the HDD is too big for fdisk I formatted it with parted.
The HDD was recognized by the OS as an ext2 disk.
I have configured the etc/fstab file to automatically boot the disk on startup (according to the instructions in the first link), using EXT2 in stead of EXT4 and setting the correct UUID.
I rebooted the device and now it is no longer recognized in my network.
The device will boot and the blue LED double-blinks, the red LED is on continuously, the yellow ethernet LED is working and there is a green LEF on the board that is on, but the device is not available in my network, it is invisible with angry IP scanner, the IP address it connected on now is unavailable.
What could be wrong and how can I solve this?

update: I reinstalled the SD card which made the device available again in the network.
I retried everything, but now formatting the HDD in ext4. The same problem arose, the device is no longer available in my network.

update: sudo blkid returns

Code: Select all

/dev/mmcblk1: PTUUID="3cedfd53" PTTYPE="dos"
/dev/mmcblk1p1: SEC_TYPE="msdos" LABEL="boot" UUID="52AA-6867" TYPE="vfat" PARTUUID="3cedfd53-01"
/dev/mmcblk1p2: LABEL="rootfs" UUID="e139ce78-9841-40fe-8823-96a304a09859" TYPE="ext4" PARTUUID="3cedfd53-02"
/dev/sda1: LABEL="data" UUID="4069503f-990e-4880-806d-172bd0165412" TYPE="ext4" PARTLABEL="primary" PARTUUID="65faaec5-3bc0-4866-b17e-184838080ad0"
my etc/fstab file contains:

Code: Select all

UUID=e139ce78-9841-40fe-8823-96a304a09859 / ext4 errors=remount-ro,noatime 0 1
LABEL=boot /media/boot vfat defaults 0 1
This breaks when I add:

Code: Select all

UUID=4069503f-990e-4880-806d-172bd0165412 /media/SATAHD ext4 defaults 0 2

Which PSU and HDD do you use?
Also recommend to use this Ubuntu minimal image since HC2 has no video output to run the Mate desktop.

Hi,

PSU is a standard 12V/2A and works like a charm.
HDD is a brand new Seagatae Ironwold 4TB.
In the meantime I managed to mount the HDD using the sda1 identifier, mounting using the UUID does not work and breaks the system.

Try to add these options (okay, the entire line - works on my HC1) in your fstab:

UUID=4069503f-990e-4880-806d-172bd0165412 /media/SATAHD ext4 defaults,noatime,nofail,x-systemd.device-timeout=3 0 2

By the way, there are not many ways to get a disk confused on a single SATA port device, so sda1 will work just as well, no need to over complicate things.

Aloha,

@vampster, were you able to show HC2 in network based on @svily0's recommendation?

I am getting ready to install NextCloudPi on my odroid-hc1. Do I need NextcloudPi with Linux OS (Ubuntu). If so would it be Ubuntu Minimal, since there's no monitor connection. Come to think about it, would NextCloud be better than NextcloudPi?

Thanks for your input...

Mahalo,
