I have Mavericks running on a 1TB fusion drive on my 2011 iMac. Having been told I can't have the eDrive on a fusion drive, I also have a 75GB partition on the HDD on which I have installed Sierra - there's 61GB space left after doing that.
Back in Mavericks I selected the Sierra partition for the eDrive, and the fusion drive as the source. During Partitioning, the Partition Map was successfully checked, but as soon as it came to 'Splitting', the job failed. Clicking the Sierra destination once more on the eDrive window it told me there was not enough free space on the volume. Not enough?? 61GB free when all the eDrive requires in total is 20GB according to the manual?
There's something very wrong here. (I've done Volume Rebuild on the Sierra partition, then tried again - same failure).
What gives?
