...That had us down for the last day and a half. That issue was related to the RAID array not being able to find half of itself after the initial dist-upgrade I performed from Jaunty to Karmic.
Right now, I'm upgrading from Karmic to Lucid, and then will move to Maverick after that. Couple more reboots are in order, plus I also need to move the server back upstairs, since it's been downstairs in my office for the past 2 days while I've been working on it.
Beyond that, I have changed passwords all around, I'm going to disable all accounts on here but mine, and hope that I don't have to reinstall everything.
I'll keep you updated.
