What *exactly* happened to your LVM PVs before the reboot ?

Presumably your RAID is fully operational, some{one|thing} has written
over the LVM metadata. At least partionally.

If just the LVM metatada and no data on /dev/sdb3 is gone *and* you've
got /etc/lvmconf/ metadata backups, you want to run:
# pvcreate -ff /dev/sdb3
# vgcfgrestore -n VGName /dev/sdb3
Before you do that or any other changes to your disks, let's make clear
what really happend first!
