Ahhhh, I missed that in the year. I wondered why the months were all jumbled up.

At any rate, you’d think they would have SOME sort of backup no matter how old.

I was going through the twitter, and it looks like upgrade was from October 2007. The twitter account went dark for over two years then came back up with the problems a few days ago.

From what I’m seeing performance tanked, new hard drives were ordered and I would assume they tried to old remove one smaller/slower drive and insert new larger/faster drive and let the array rebuild which should have gone fine, unless the remaining drive had a hiccup, but that should have broken the array not wiped the file.

There isn’t much info in the twitter. More information would be nice so we can all analyze what happened.

Looks to me from their twitter they were in the middle of an upgrade and it went bad… very bad.

Always break a mirror before a major upgrade– especially if you don’t have backups.
