As planned, this September we doubled the RAM in our main hypervisor at home from 128 GiB to 256 GiB.

As per Ubiquiti’s support article EdgeRouter - Add Debian Packages to EdgeOS, I enabled some apt sources on my EdgeRouter 6P.

I had a bit of trouble adding an ssh key to my Ubiquiti EdgeRouter 6P. I kept getting

Not a valid key file format (see man sshd) at /opt/vyatta/sbin/vyatta-load-user-key.pl line 96, <$in> line 1.

Turned out that the key needs to:

• have a comment
• not have any spaces in the comment
• be on a line of it’s own in the imported file (e.g. do not add a newline at the end)

for loadkey to accept it.

It’s been about 2½ months since I started adding ODROID-HC2 nodes to my Ceph Luminous cluster.

This is a quick update on how it’s doing so far.

Just the steps needed to grow a cached LV.

I was gifted a SoftIron OverDrive 1000, an ARMv8 Opteron Seattle based machine.

This post is my braindump. Expect it to change until I remove ‘WIP: ’ from the title.

I built a Ceph Luminous cluster containing seven ODROID-HC2 nodes. This cluster also contains some x86 VMs running on my hypervisor.

I use this cluster mainly as a Ceph playground.

For Ceph use I definitely did not want to mess about with serial console on the ODROID-HC2 (there are 7 nodes to install, there could be more). The instructions include getting rid of the need for serial console during first boot.

Since I seem to set up new Sailfish OS devices at least once a year (because I got myself a new toy) and I am lazy, I set up my current Sailfish OS device, a Gemini PDA, up to work with Ansible.

These are my notes on using Ansible with my Gemini PDA running Sailfish OS 3.0.1.14

For some reason, Sailfish OS on a Gemini PDA has a very small / but an overly large /home/.

This post describes how to reclaim space from /home/.

After installing Fedora 29 on my ODROID-HC2 nodes, I want to get an ansible user onto them so that my usual Ansible playbooks can configure them.

This blog post is about installing Fedora 29 on an ODROID-HC2 (from a Fedora 29 x86_64 workstation).

The aim is to get the ODROID in a state where one can ssh as root to the host.

Both initial setup over serial and installing without using a serial console are described.

Added this to my server:

• Supermicro 2-Port NVme HBA AOC-SLG3-2M2-O
• 1000GB Samsung 960 Evo M.2 2280 NVMe PCIe 3.0 x4 32Gb/s 3D-NAND TLC Toggle
