(Re-) Partition on hAP ax² - Normal workflow?

Hi,

I repartitioned the internal Flash of my hAP ax² for getting two partitions with one being a "Backup" partition. At the end I was successful but I had some pitfalls.

In the documentation there is a short description why two partitions would be helpful as "Backup" and the commands for repartitioning and some restrictions from 7.20 on. What is missing in my eyes is the repartition process itself step by step.

Here in the forums I found a statement that one only needs to change from one to two partitions and afterwards the device would boot into the old configuration - just with two partitions and the possibility to use the second partition as backup. This was not the case with my device.

The repartitioning made me familiar with netinstall and the backup bootloader: After I changed the device-mode and changed the partitions from one to two the device simply hang in a boot-loop. After reading a short introduction to netinstall I got the device reinstalled with the previous config again using netinstall-cli.

The strange thing to me was that the configuration seemed to be extractable from the first / the old partition. But the device was no more bootable from that partition (0). Netinstall installed the version to the new partition (1). At the end I copied the content of the new partition with the configuration to the old partition to make this one being bootable again.

My question: Is this "works as intended"? This would be OK for me if this would be documented a bit more detailed. I was a bit "shocked" for a short moment when the device ended up in the boot loop.

The version was all the time 17.19.3: RouterOS and netinstall.

Thank you!

It is a bug. It used to work, but I had the same experience when I set a CCR1009 from 2 to 1 partitions: it crashes during the boot.
I netinstalled it (not so easy in itself due to another issue that has been fixed in the meantime) and did not further experiment with it, I am not the software debugging department of MikroTik.
But sure there is a problem and people wanting to change back to 1 partition should be prepared to netinstall.
(so do not attempt it from remote, or when longer downtime cannot be tolerated)
