Hmm, weird; I also tried just copying the disk, and I could not.
Fiddling around, I forced SPM over to another node, and copy worked, so
I tried cloning again, and that worked too. Guess something needed a
"reset".
Do you have the logs from the original spm? Checking them may explain why
the chain was legal.
Sound like an operation was interrupted, and it took some time to clean up
chain, but this is only a guess.
