I'm running Clondeploy 1.3.3 and I ran into an issue with imaging iMacs with Fusion drives. First let me say we have run into countless issues with these hybrid pariahs. So I was able to create an image from a MacBook Air running High Sierra. I was also able to image these iMacs with this image. However, we have discovered that even though we can image these devices if they are running on a traditional hard drive (or worse Fusion drive) then they slow down to nearly unusable.
I tried to make an image on one of these devices and upload it to CloneDeploy, but the upload fails. I have a feeling that this has to do with core storage and how CloneDeploy is determining drive size. I've attached a log of the failed upload.
