It's probably going to take a while, my guess is probably a week. Here is what the pastebin linked no the main page says.
> We believe one of the HDDs in the raid group is failing, as such the I/O wait is unacceptably high. The site and ftp might be temporarily offline while I'm assessing the situation and moving things over to a new server. We do maintain backups, internally as well as some community members, so nothing is lost or gone. If the old server is in an acceptable enough state I will start it back up in some limited capacity while we perform the transfer. - Sunako (qq is at work or something)
>P.S. Pastebin sucks
>The rsync is proceeding slowly, we're about 1/3rd of the way onto the new server. No definite ETA since network conditions are generally unpredictable, but probably 2-3 days. The site and ftp will remain online in a somewhat reduced, but generally accessible, state for the time being during the transfer. I'll update when we're around 2/3rds of the way there, unless anything new or amazing happens before then, in which case I'll update sooner.

So it is going to take a while, but it's better than the server crashing. This is also what the main page of madokami says when you go onto it.
