Everything works if I provide a username. I didn't specify a username in my /etc/fstab file and it hung. Everything else hung after that and couldn't be killed. I found this: https://github.com/rear/rear/issues/149 which pointed to tcrypt not being loaded. I used: modbprobe tcrypt and it said it was temporarily unavailable. I decided to add a username to fstab and restart the machine. Everything mounts and mounts after reboot work and don't hang. I appreciate your help.
