I'd like to install a Linux distribution alongside OS X on my 2014 5k iMac with a 3TB Fusion Drive (128GB SSD + 3TB HDD).
Most guides about dual-booting Linux I've found focus on regular partitioning, that is, no Core Storage, and I couldn't find one that helped.
I want to keep OS X in case I have to use software that isn't available on Linux, like XCode or PhotoShop.
My goal is to use Linux as my main system, and I want the root (
/) partition to live on the SSD to speed up boot, and the home partition to be on the HDD.
Here's the potential solution I found (haven't tried yet):
- Split the Fusion Drive
- Download and install OS X El Capitan on the SSD from the recovery partition
- Boot into El Capitan
diskutil cs revert <UUID>on the Logical Volume which should be marked as
diskutil cs list
- Resize the HFS+ OS X partition to around 60 GB
- Install a Linux distro (Ubuntu, at first) on the free space
- Create another partition on the HDD for
- If it's possible, assign both partitions to a volume group using LVM
Is this possible, or have I missed something that will make it fail?
