Hetzner CHR issue

Tue Nov 03, 2020 10:24 am

Hello guys,

I tried to install CHR on the Hetzner cloud, based on https://wiki.mikrotik.com/wiki/Manual:CHR_Hetzner
but I get no hard drive found after reboot.

Pasted File at November 3, 2020 10_43 AM.png

I tried many different versions with no success.

How can I fix this issue?

Hello,

thank you for reaching out to us. We just tried with the newest stable version 6.47.7 (https://download.mikrotik.com/routeros/ ... .7.img.zip) and the above mentioned Hetzner manual and CX11 cloud VM and it worked as expected. Please try again.

Try of=/dev/vda
If I remember correctly that helped me with Aruba Cloud.

My disk located at /dev/sda

Ok. Short googling tells that you need forced reboot at the end of procedure, not the "regular" one:
Code: Select all
echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger
From here (in Russian).

the same result, it can't detect the disk.
Also, I tried the power cycle from the panel.

RouterOS v6 kernel does not support AMD EPYC CPU's, please use CX instances (Intel Xeon based ones), instead of CPX instances which are using AMD EPYC

You can use v7 beta with the CPX instances:

This is V7 beta.
Did you try V6?
