Q: FileVault stuck on "Encryption Paused"

i just tried these steps and now filevault is decoding!

1. reboot
2. reset pram with option+cmd+p+r
3. booting with cmd+r the utility disc
4. select the partition encrypted
5. click file and unlock
6. repair the partition disk
7. repair permission on partition
8. repair macintosh hd
9. select the partition encrypted
10. click file and decoding if clickable (months ago was grey and this procedure did not work!!!)

a warning told me that the decoding was started!!! I hope someone can solve the issue with this procedure!

...now I can install El Capitan

sorry:

10. click file and "turn off encryption"

So like many others......my Mom's Filevault magically started today. I actually went to her house to try everything listed here....and when nothing seemed to work, I started taking backups to prepare to re-install (she had TM, but I like multiple copies).

After copying about 200GB off the machine, I went to re-install and I checked Filevault one last time and was shocked it was working.  We did have a long Optimization period afterwards......but it did finish.

Wish I could offer help on what happened......but we just don't know.

Just wanted to mention this one again. It totally worked for me. The Disk Utility included with the El Cap installation is the 'updated for El Cap' version, and First Aid was able to find and fix the problem. I restarted, and encryption resumed, and was finished in just a minute or two. Score.

1-I created a bootable disk with the DIY option at this link http://lifehacker.com/how-to-burn-os-x-el-capitan-to-a-usb-flash-drive-173342513 3 the el capitan app is already downloaded so I used this.

2-I booted to usb with pressing option key at start up.

3-after language selection I clicked on disk utility

4-I unlocked the disk and while it is selected I clicked the first aid button at top.

 

At the process it said something about paused encryption and expanding partition. At that point I realized the problem is solved. I restarted the mac regularly and then I saw encrypting instead of paused.  after the finished process I was able to install el captain and I was able to get rid of this paused encryption problem.

I am glad that worked for you

Did you ever figure out a solution to this?  My terminal log shows pretty much the exact same thing...  The drive appears to be non-revertible.

Thank you so much for suggesting this fix. It worked flawlessly for me. I had been stuck with an unresponsive FileVault for almost 9 months until this post. Successfully upgraded to El Capitan as well.

You have my absolute gratitude, buddy!

I ran into this same problem after installing El Capitan on a blank SSD on my Mac Mini. I enabled FileVault, restarted, and it stayed stuck at "encryption paused" no matter what I did. I tried resetting the PRAM, running First Aid on the unlocked partition, reinstalling OSX--everything suggested in this thread. After several days of trying, I finally had the thought that the UPS might be the problem, since OSX will pause the encryption based on the power source (usually this would only affect laptops, but there's clearly a bug in El Capitan). I unplugged the USB connection to the UPS, restarted and sure enough, the encryption process finally started. So for anybody that runs into this problem on a desktop connected to a UPS, try disconnecting the data cable and restarting--even if it doesn't say anything about connecting to a power source.

This worked for me as well.

A small note: once you reboot with your USB in, you need to first select the option to Install El Capitan in order to be able to unlock your disk (at least that's what I had to do). Once you've done that, don't wait for the install procedure to end (it won't) but rather click back, go back to selecting Disk Utility and then run First Aid on your volume (usually "Macintosh HD", I guess).

In my case, one of the logs from First Aid said "The volume xyz was resized to unblock Paused encryption". First Aid ran for less than 5 minutes on my SSD drive. Once done, quit everything and restart normally.

My filevault was stuck at the end of the encryption process, so after the second restart, I checked its status, unlocked Filevault's setting page, it took about 30 seconds to calculate the estimate time remaining, it then said "8 minutes" and after a couple of seconds :-) it actually finished the encryption. I got about 30 painful seconds of spinning beachball, then all went back to normal.

This helped me after having the curse for 9 months, thank you!

Awesome!!! This worked perfectly.

Yes, this may be caused by the UPS bug in El Capitan.

I've had the same issue on a brand new machine, and Disk Utility repair did not help.

I remembered seeing the issue about Time Machine backups not working when a UPS was connected, and sure enough, when I disconnected the UPS and rebooted, Time Machine started working and FileVault continued encrypting.

So, if you are having this problem with El Cap, disconnect your UPS and reboot.

I had unplugged my UPS thinking the same thing as you and was disappointed to see nothing change then ran another backup. I came across your post to reboot and voila! It worked, Muchas gracias!

This worked for me!! Thanks!!

still does not help.
