The ~~Ceph Nix package has been hard-pressed to keep up with Ceph, as filesystem concerns are a larger challenge on NixOS than on other Linux lineages. This is a problem seeking a solution~~; read ahead to see some of the remaining issues this guide should address. Please make a Wiki account and add your experiences~~, if~~ you ~~made progress running a modern Ceph version~~.

The below wiki instructions still have some troubles; read ahead to see some of the remaining issues this guide should address. Please make a Wiki account and add your experiences.

Another distributed filesystem alternative you may evaluate is [https://github.com/seaweedfs/seaweedfs SeaweedFS].

Here is a quick collection of commands I used on a 3-node Ceph mesh.

The examples have been reduced to a single node, `mesh-a`, for simplicity.

Describe your ceph user, alongside your normal login user:

Line 32:

enable = false;

extraConfig = {

"mon initial members" = "mesh-a~~,mesh-b,mesh-c~~";

"mon initial members" = "mesh-a";

"mon host" = "10.0.0.11~~,10.0.0.12,10.0.0.13~~";

"mon host" = "10.0.0.11";

};
