CoreStorage: what does LVG status 'offline' and PV status 'checking' mean and how can it be fixed?

CoreStorage: what does LVG status 'offline' and PV status 'checking' mean and how can it be fixed?

I converted a partition to a CoreStorage volume using this command:
sudo diskutil cs convert disk0s2 -passphrase test123
Now when I run `diskutil cs list' the output shows that I still only have a Logical Volume Group and a Physical Volume attached to it. The status of the LVG is 'Offline' and the status of the PV is 'Checking'. It has been this way for over 10 hours on a 128GB SSD.
To me it seems this status indicates some kind of intermediary status, as if the conversion/encryption has not completed yet, is that assumption correct?



In Disk Utility.app the disk name is shown in red! I can run the Verify Disk command and the output seems ok (ends with 'The volume {UUID of the LVG} appears to be OK' and 'The partition map appears to be OK').
But in the output of Verify Disk I see mention of a logical volume ('Logical Volume Group contains 1 Logical Volume'), which the output of diskutil cs list does not show. And following that, I see mention of two UUID's to which diskutil cs info {UUID} responds '{UUID} is not a CoreStorage UUID'.
To me this seems inconsistent, and I'd like to resolve this.
