Reconnecting your LXD installation to the ZFS storage pool

You are using LXD and you are creating many containers. Those containers are stored in a dedicated ZFS pool, and LXD is managing this ZFS pool exclusively. But disaster strucks, and LXD loses its database and forgets about your containers. Your data is there in the ZFS pool, but LXD has forgotten them because its …

Scaleway has been offering ARM (armv7) cloud servers (baremetal) since 2015 and now they have ARM64 (armv8, from Cavium) cloud servers (through KVM, not baremetal). But …

How to initialize LXD again

LXD is the pure-container hypervisor that is pre-installed in Ubuntu 16.04 (or newer) and also available in other GNU/Linux distributions. When you first configure LXD, you need to make important decisions. Decisions that relate to where you are storing the containers, how big that space will be and also how to set up networking. In …

It is a process that works, but makes it cumbersome because LXD also expects some other features in the Linux kernel. See https://blog.simos.info/how-to-run-the-stock-ubuntu-linux-kernel-on-scaleway-using-kexec-and-server-tags/ on  a trick to run the stock Ubuntu Linux kernel in a Scaleway VPS …
