My hosting provider WebFusion updated my VPS with security patches late last night.
Since then I cannot start my ejabberd instance. I get the following errors, which seem to indicate that the hostname has changed.
=ERROR REPORT==== 2010-11-29 23:01:10 ===
E(<0.35.0>:ejabberd_config:278) : Error reading Mnesia database spool files:
The Mnesia database couldn't read the spool file for the table 'acl'.
ejabberd needs read and write access in the directory:
/var/lib/ejabberd
Maybe the problem is a change in the computer hostname,
or a change in the Erlang node name, which is currently:
'ejabberd@lvps109-104-93-116'
Check the ejabberd guide for details about changing the
computer hostname or Erlang node name.

Everything has been working a treat for many months and I have made no changes to the VPS configuration, which is based on Ubuntu 8.04 LTS by the way.
I have tried everything I could find on Google w.r.t recovering or migrating mnesia files in this type of scenario, but I cannot seem to get the instance started again. I cannot make a binary backup of the files and clean-slate the system since this relies on getting a running instance up before the backup can be completed. It looks like I am stumped and will have to write-off months of user account registrations.
My hostname does not appear to have changed with the patches and reboot that the hosting company performed. Honestly, I don't really know what hostname ejabberd is expecting but I know it is of the form ejabberd@. Is there a way I can determine this from the existing mnesia data files I wonder?
As for the technical support channels of WebFusion? They have told me in no uncertain terms that I am on-my-own and offered no support at all when questioned.
Would appreciate any guidance on how to extract the data from the mnesia data files in /var/lib/ejabberd and how to recover this or a new installation. I will consider moving to a new host or VPS if I have to.
Very many thanks in advance.
