OK, so the reason my Jabber server went crapola a few weeks ago was because of the fuckedup nature of the disk setup. (Recent outages were down to power issues)
I'd like to rectify this.
So, Linuxistas, here's the challenge: un-LVM a Debian/Ubuntu system without reinstalling it.
I don't even know whether it can be done, but I'd be interested to hear your thoughts.
