I'm having a bit of trouble here. I'll try and be as concise as possible in describing my objective:
I'm setting up a storage server for my employer, using two Intel DC S3500 series 120GB solid state drives (and 12 x 2TB SAS drives for storage). I would like to install freebsd10 with root-on-zfs on these drives, but only use a small (12GB) partition to create a zfs mirror for the OS. The remaining space, I want to use for a ZIL/SLOG (24GB), and the rest for a L2ARC (striped, everything that's left, on both drives).
I cannot figure out how to tell the freebsd10 installer to only use 'ada0p2' and 'ada1p2' as my mirror for installing the OS onto. I only get the option for using the entire drives.
Additionally, I've tried installing as normal and then using zfs send and recv to backup, resize the partition with gpart, and then restore a replica stream of my zroot pool... the system refuses to boot when I do that.
How do I go about achieving this goal? Any assistance with this would be much appreciated.
