So you're saying you accidentally deleted the device nodes in /dev, but you did not actually delete the contents of the Volume Groups, nor did you modify the partitions containing the physical volumes?

Try running dmsetup mknodes and see if the missing device nodes reappear. You could also try restarting udevd, but the procedure for doing that varies depending on which distribution you're using.

Those device nodes are created by the system on the fly when booting. A simple reboot should fix your issue.
