I have a Mac mini with 2 disk, and I wanted to encrypt the second (non-boot) disk. I used Finder's right click > Encrypt to start the encryption process. However, it seems to be stuck.

diskutil cs list outputs:

CoreStorage logical volume groups (1 found)
+-- Logical Volume Group 51...
    Name:         Macintosh HD

        Status:   Checking
        Size:     998999998464 B (999.0 GB)

and diskutil cs info 51... outputs:

Core Storage Properties:
   Role:                       Physical Volume (PV)

   PV Status:                  Checking

It has been stuck on "Checking" for quite a while, and looking at Activity Monitor shows no processes using CPU or Disk, leading me to believe it has gotten stuck. How can I move forward and get my disk out of this situation?

Edit: Checking the Console, I keep seeing the message debugPortal: kCoreStorageGetGroupSparseState invalid lvg uuid pop up every second.

Edit 2: The disk has now disappeared from the Finder and Disk Utility, however it still appears in diskutil and diskutil cs, though no diskutil cs commands work, they just say the UUID is invalid.

  • How long is "quite a while"? This is one operation you don't want to interrupt until you're absolutely certain it's completely stuck - unless your backup is completely up to date. – Tetsujin Nov 21 at 19:44
  • @Tetsujin I do have a backup but I'd like to avoid having to restore if possible. I didn't pay attention to the exact time I started it, but it's been about 2 hours now. I would expect it to be doing at least something though, maybe running fsck_hfs or something, but I see absolutely no sign of anything running. Also, see my update on the Console message. – At0mic Nov 21 at 19:49
