Data Node Won't Start: Internal program error (failed ndbrequire)

During a nightly backup that has run without problem for many years, my entire NDB cluster crashed. The cluster has two data nodes and I was able to restart one of them this morning, but it looks like a day's worth of data has disappeared. The second node will not start. I get this error message:

Can someone please tell me what I need to do to start the second node?

Thanks much!
