For a while there has been an update to MyMovies that I have been meaning to install. On Saturday, I decided to do the upgrade. The first thing that I did was uninstall the old Windows Home Server add-on. The uninstallation appeared to go OK, and I was prompted to reboot the server. Once I did, the server would not fully boot back up. Since this is a HP MediaSmart ex475, and there is no video out, the only option is to recover the server. Since server recovery consists of reinstalling the server software, I decided to to take this opportunity to upgrade the system drive to a 1TB drive that I had, but hadn't used.
Reinstalling the software went fine, but I was never able to get it to automatically recover the data from the other drives. Supposedly, when you do a server recovery, the data will be automatically reconstructed from the drives.
Instead, the server partition is created, and all of the other drives are just mounted, but not added to the storage pool. No data is lost here, but you just need to copy the data back to the storage pool. This page describes the steps required to recover data. I am using GoodSync to do the copy, as it pretty much functions like rsync, but doesn't require cygwin. The copying of the data will take a few more days.
