Hi All,

I have an APFS volume named Photos (disk4s1) that will not mount, states it is locked, and is stuck at 10% encrypting. When I enter what I think is the correct password, its status changes to "Not Locked" however it is still inaccessible and will not mount, and yet continues to request the password.

In summary as of right now, the encryption process is on hold at 10%, and when provided the passphrase the only change is the status is changed to "Not Locked" but it is still unmountable. I have been adding some SSDs to the 5,1, so I wonder if the APFS containers are confused. Below is the output from diskutil apfs list:

Any ideas would be appreciated. I think they are backed up at another location, but would like to make sure before nuking it. :)

OS is OS X 13.6

You'd be safe to perform the operation with ~500GB free space.

I believe this was only true in the case of Legacy Filevault (that is, when it still used disk images), but I don't believe this level of free disk space is required for the modern version of FileVault.

Even so @monkeybagel, I suspect your problem is caused by either low disk space or (less likely) some kind of disk error. I searched around and it looks like many people have had this problem, but no one was able to solve it; they all erased their disks or reloaded their systems entirely. I'm not sure there is a solution.
