I'm trying to make a homebrew FD of 500GB HDD and 128GB SSD. I'm using Maverics 10.9.1 and MD101 MBP.
What I did was:
- install HDD into superdrive bay
- install SSD into HDD compartment
- use
diskutil cs convert
on HDD to make it a CoreStorage Logical volume - add SSD into the logical volume with
diskutil cs addDisk
- resize Logical volume to use all available space on both SSD and HDD with
diskutil cs resizeVolume
What I can see now is a volume that has a capacity of summary capacity of SSD and HDD, but iostat
shows that SSD load is zero. No matter what I'm doing - copying files around, downloading new files, etc. it remains zero (here disk0 is my SSD, disk1 is HDD and disk3 is a USB drive with TimeMachine backups):
disk0 disk1 disk3 cpu load average

Don't think that it's normal, but who knows. Has anyone faced such problem? What have I done wrong?
