yes, we still have some socket F / nvidia motherboards in production. branch needs a reboot to see the new drives, because the nvidia sata driver sucks.
We're using the 'xm save' capabilities, so for most of you, you will see 10-20 minutes of being offline, then you will be back, without experiencing a reboot.
for those running netbsd or debian derived distros, if you see problems, do a reboot. Debian5 xen kernels tend to recover poorly from a xm restore.
We will attempt to go though people's console on startup and catch these problems for you, but just in case, all of the restore-related badness can be fixed with a reboot.
Again, most of you shouldn't have to worry about this; it should just work.
edit: we're running some final checks, but you should all be back now.
everything looks good. I'm rebuilding the raid. expect poor disk performance for the next 900 minutes or so.
edit: the raid rebuild is done; everything should be back to normal. let us know if there are problems.
