Time Machine Encrypting Backup Disk stuck at 0%

I set up a new Time Machine backup for my iMac and it has been stuck on Encrypting Backup Disk 0% for a few days now. Is there something to be done about this? Should I reset it somehow?

iMac 27", macOS 10.14

I am seeing the exact same behavior, with mine progressing at the snail's pace of about 2%/day thus far. It is a 10TB backup disk, so I guess maybe I should just be patient. I did see suggestions elsewhere to encrypt the disk ahead of time with Disk Utility, but TimeMachine just undid everything I did and did it on its own anyway. So, I've just been letting it run. I usually put the system to sleep at night, but I've just been letting it run with just letting the screen sleep.

Aha! Wisdom emerges. Turns out diskarbitrationd and the Western Digital software were having a head butting contest. After some web reading it turns out this is not an uncommon occurrence. I ripped out all the WD stuff (I should have known better than to install third party disk management stuff anyway) and it finished up. Checking the console logs, it was generating several messages per second between the two of them. *doh*
