In my 5,1 mac pro, I have a Sonnet M.2 4x4 PCIe card with two 2TB nVME SSDs configured as a JBOD concatenated set that I use for storing VST audio libraries. I started running out of space so I just added a new 2TB drive. After rebooting, OSX (Mojave) ask me to initialize the drive and I used Drive Utility to add it as a slice to the JBOD set. After it was done, it reported there was an error. Even though the volume set now reported as 6TB, something didn’t seem right. I thought maybe I should have initialized the drive as APFS first prior to adding it to the set so I removed the slice and reformatted it. When I tried to add it back in, I noticed that the set reported it was missing a slice (the one I removed) and without it, the set won’t mount. I’ve tried remove this ‘zombie” slice with diskutil’s GUI and the command line, but it won’t let me. Since the new drive was reformatted, it was assigned a new UUID so it doesn’t recognize it as the missing slice.
Playing around with diskutil, I was able to add the new nVME drive as a slice, but now the set says it has Four slices including the previous zombie. The volume still won’t mount or let me remove the slice. So now I have:
Does anyone have any knowledge on how to fix this?
Here is what diskutil reports:

- slice 0: 2TB full
- slice 1: 2TB almost full
- slice 2: zombie slice reported as missing/damaged
- slice 3: 2TB completely empty
