Moving from Lunix (mdadm) and a RAID-10 array

Greetings

I've been running what most linux enthusiasts call an overly complicated system (grin - - but its belt and suspenders and I works quite well thank you very much!!!).

So in the process of moving from Linux (mdadm) and a RAID-10 array - - - - how do I set up ZFS - - - I'm assuming Z2 (don't think I'm really needed a 3rd level of redundancy like Z3)?

steps:
1. copy everything on the array to another disk.
2. wipe discs (there are 4 in the array)
3. assuming Z2 how do I use all 4 discs - or can I even?

(Is even Z2 the best place for me to be?)

TIA
 
The ZFS raid10 equivalent is probably more performant than raidz2, but only survives 1 disk failure guaranteed and a second one maybe.
 
raidz2 will have the same storage capacity as 2x zpool mirrors but better recoverability and worse performance. Another thing to consider: with mirrors you can replace 2 disks (with larger ones) of one mirror (to gain more disk space). With raidz2 you will have to replace all four disks to increase disk space. There are online tutorials that will show you how to implement either.

Do you plan to put root on this 4 disk zfs filesystem or is that separate?

Make sure you verify your backup during the transition to zfs!
