Are /dev objects required for clean shutdown?

/dev on my CentOS 7 box took a 'rm -rf' yesterday, wiping out most of it. Easiest way to recover is to reboot (/dev is on a ramdrive and created from scratch during boot), but I'm worried about not getting a clean shutdown. Does cryptsetup need anything in /dev to shutdown cleanly? If so, how do I recreate the devices? The complete list of what is missing from /dev is huge, but the below all seem to be disk related and are all gone now:

/dev/dm-0
/dev/dm-1
/dev/dm-2
/dev/sdb
/dev/sdc
/dev/sdd
/dev/sg0
/dev/sg1
/dev/sg2
/dev/mapper/luks-27bc6c3f-3479-4c65-b2f8-17d35081bbf4
/dev/mapper/luks-2f41b83f-925d-42f0-aca2-b91b1c6265b0
/dev/mapper/luks-68f22741-5399-41e5-b40b-81230cb51b27
