if you are running multipath then here is what happened, multipath started up and attempted to manage sda and so it deleted sda1, then once it gets to sda2 it figures out the vg is live and online and it figures out it cannot manage it, so stops. No code exists apparently to go back and put back sda1 in some versions. partprobe will work, but without partprobe sda1 won't exist, and the uuid links will be pointing to something that does not exist.
