Hi guys
I'm currently planning to upgrade several parts of my system and need your help on how to do this.
My current system is what I call the “IKEA NAS” (http://imgur.com/a/bQ7De), running a 6x4TB z2 Pool, 16GB RAM and on an Intel Atom CPU. The CPU will brick itself in the foreseeable future and the space is used up to about 85%.
Because of this I'm planning to upgrade to a proper serverrack, probably a supermicro one with 24 or more LFF drivebays.
After doing some research, I've decided to go with an 11x4TB z3 Pool, which will get a twinbrother once the need arises. This will give me around 30TB per vDev and 60TB of usable space in total.
Now comes the tricky part: how to do this transition “smart”.
I see two main options:
1) Add in a second vDev to the current system (and striping them together) and thereby solving the storage shortage and buying some time to find a proper replacement. Then getting the new system with 11 drives, migrate the current pool (2x 6x4TB z2) to the new system (the z3 pool), trashing it, build a second z3 pool and stripe them together.
2) Getting the new system with 11 drives, migrating all the stuff to the new pool and keeping the old drives to build the second vDev later.
Since this was my first build, some mistakes were made and I will not reuse the configuration but instead have a clean start. So I want to put the old drives in a new, fresh installed system.
How would I go about option 1)?

- Get 6 new drives
- Simply “slap” the two vDevs together (stripe) to extend the pool? Or is there more to it?
- Get the new rig with 11 new drives
- Detach both vDevs from the old system
- Take the current 12 drives, put them in the new system
- Attach the old vDevs
- Migrate the data from the old vDevs to the new vDev
- Destroy the old vDevs
- Build a second vDev with 11 drives
- Stripe both new vDevs together, resulting in one new big pool with all data and 60TB capacity
- Get the new rig with 11 new drives
- Detach the vDev from the old system
- Take the current 6 drives, put them in the new system
- Attach the old vDev
- Migrate the data
