Cannot turn off FileVault process in terminal or DU in macOS High Sierra Worst mistake of my life upgrading to High Sierra. At first I couldn't use Time Machine with error 11 and so I decided to try FileVault to encrypt my SSD and it's been going for a week, stuck at 10%. Unbelievable it can't be stopped in terminal. See below:

typed fdesetup status to check progress Encryption in progress: Percent completed = 1?  been over a week now

typed fdesetup disable Error: This command requires root access.


This is actually a different message from yesterday when instead it asked me for a password and then username and then I got a filevault not disabled (-69573) message. 

Does anyone know what that number code means?

All I want to do is turn this damn thing off and attempt another Time Machine backup. Any help is greatly appreciated.
If you're on a laptop, make sure it's plugged in as FileVault will pause on battery.  If that's not causing it, you can create a clone of your system using Carbon Copy Cloner (http://www.bombich.com/) or SuperDuper - that's what I would do - and then wipe the system, re-install the OS (High Sierra isn't that bad).  Then I would enable FileVault on the clean system, wait for it to finish encrypting what little is there (OS only, a few gigs), then restore your files from the clone manually, then enable Time Machine and have it do its backups.
