mod_storage_metronome_readonly

Introduction

This is a storage backend using Metronome Lua storage.

This module only works in read-only, and was made to be used by mod_migrate to migrate from Metronome’s storage.

So far it has only been tested migrating to sqlite, because mod_storage_internal relies on the same data_path variable as this module, and thus would overwrite the files we just read.

I’ve also only tested it on a dump from a Metronome configured by Yunohost, so using LDAP and such for user accounts, I don’t yet know how to migrate from different Metronome account storages.

Configuration

Copy the module to the prosody modules/plugins directory.

In Prosody’s configuration file, set:

storage = "metronome_readonly"
data_path = "/var/lib/metronome"

To run the actual migration, run these two commands (replace <host> with the domain you want to migrate):

prosodyctl mod_migrate <host> roster,vcard,private,cloud_notify,pep,pep_data-archive,offline-archive,archive-archive,uploads-archive sql
prosodyctl mod_migrate muc.<host> config,persistent,vcard_muc,muc_log-archive sql

It will create a file in /var/lib/metronome/prosody.sqlite, after which you can change your configuration file to point to it, or alternatively you can perform a second migration to the internal storage if you prefer that.

Compatibility

sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_storage_metronome_readonly
